diodes inc (DIOD) Key Developments

Diodes Incorporated Introduces the DMN3027LFG 30V N-channel MOSFET

Diodes Incorporated introduced the DMN3027LFG 30V N-channel MOSFET. This device is designed as a switch to rapidly and safely discharge large bulk capacitors used on FPGA power rails. The latest FPGAs found in telecoms equipment, servers and data centers have multiple power rails that need to be correctly sequenced to safely power these systems up and down. Designers of high-reliability DC-DC power supplies can achieve this quickly and easily with this new MOSFET from Diodes. The DMN3027LFG has an RDS(on) of 26m© at 4.5V, which is low enough to discharge a 15mF capacitor in ®3333 package, which has a low thermal resistance from junction to exposed pad of PowerDI is a registered trademark of Diodes Incorporated.

Diodes Incorporated Introduces the AH37xx Family of High Voltage Hall Effect Latch ICs

Diodes Incorporated introduced the AH37xx family of high-voltage Hall effect latch ICs. These provide various operating magnetic thresholds to address motor control, rotational position, and speed-sensing requirements such as controlling the commutation of brushless DC (BLDC) motors in washing machines, dishwashers, fridge-freezers, air-conditioners, food processors, power tools and cooling fans; the measurement of speed in motors, pumps and flow meters and contactless position sensing/indexing in printers, scanners, and window blinds. Spanning industrial and consumer applications, the AH37xx family is designed for 3V to 28V operation and integrates a reverse-blocking diode, Zener clamps on input/output pins and an output current limit to help provide protections from transients and overload. An extended temperature specification, from -40oC to +125oC, and a low temperature coefficient ensure reliable operation at the switching threshold points while a 6kV ESD capability improves robustness and allows easier handling during manufacturing. System design flexibility is achieved with different magnetic operation and release thresholds (BOP and BRP) within the family: the AH3772/4 and AH3781/2 provide high sensitivity with BOP and BRP of +25G/+40G and -25G/-40G, the medium sensitivity AH3775/6 parts are rated at +70G/+110G and -70G/-110G, and the AH3777 is the least sensitive with a +140G and -140G specification. The designer is also offered a choice of output configuration, between the open-drain AH377x series and the AH378x parts, which have an internal pull-up resistor to lower BOM count and save board space.

Diodes Incorporated Introduces 100V MOSFETs Optimized for PoE Applications

Diodes Incorporated introduced the DMN10H120SFG MOSFET. This device is designed as a switch for IEEE 802.3 compliant 48V Power-over-Ethernet (PoE) systems. This switch enables the delivery of power through the Ethernet cable to end-applications such as wireless access points, VoIP phones, point-of-sale terminals, call systems, IP security cameras and building management devices. In power-sourcing equipment such as LAN routers and midspans, this 100V N-channel MOSFET switches power to the CAT5 (or CAT6) network cable. The cable then provides both power and data, which reduces system costs by eliminating the power supply in the end-equipment. It also protects end-users because PoE operates between 44V to 57V, which meets the 60V Safety Extra Low Voltage (SELV) rating, which removes the need for rigorous isolation and certification of end-equipment while also easing system maintenance. With a 100V BVDSS rating the DMN10H120SFG MOSFET provides plenty of headroom for 48V PoE operation. The DMN10H120SFG also offers an extended safe-operating-area (SOA) that can withstand the power dissipation due to short-circuit fault conditions, such as an Ethernet cable breaking, until the PSE controller detects the fault and switches off. During this fault condition the MOSFET goes into linear mode and needs to dissipate 30W for at least 20ms, which is achieved even with a +60°C elevated operating temperature. The DMN10H120SFG is offered in the space-saving PowerDI3333 package. Within its extensive 100V DMN10H family, Diodes also offers SOT23, SOT223 and TO252 (DPAK) packages. The avalanche-rugged DMN10H099SK3, for example, in TO252 is 100% unclamped-inductive-switch (UIS) tested to ensure it can withstand the energy pulse in switching inductive loads such as coils, motors and relays.

Diodes Incorporated Introduces AZV5001

Diodes Incorporated introduced the AZV5001. This headset detection IC is targeted at cost- and power-sensitive consumer electronics such as mobile phones, tablet computers and media players. The integration of a comparator, OR gate and N-channel MOSFET into a miniature package enables the connection of a headset with microphone to be quickly and simply detected. The AZV5001 has two detect inputs that together determine when a headset has been inserted into the equipment’s audio jack. The presence of a left audio signal drives the internal comparator output low, which when logically OR’ed with a ground connection from the jack will result in a low output from the IC, indicating the headset is properly connected. Internal pull-up resistors on both detect inputs ensure that connection is not indicated when either signal is absent. When a headphone is not detected, an on-chip N-channel MOSFET is enabled, which can be used to mute the microphone input to the equipment’s audio codec. A miniature 6-pin 1.2 mm x 1.0 mm x 0.4 mm DFN1210H4-6 package helps the AZV5001 reduce board space. A low supply current, typically 7.5µA when operating from a 1.8V supply, reduces system power consumption while low voltage operation, down to 1.6V, is also supported.

Diodes Incorporated Introduces 1MHz, 2A DC-DC Buck Converter, Enables Efficient, Small Form-Factor Designs

Diodes Incorporated introduced the AP3402, AP3419 and AP3429. These DC-DC step-down converters operate from inputs of 2.7V to 5.5V to supply loads up to 2A, with great efficiency under both light and heavy load conditions. A high switching frequency of 1MHz reduces the size of external components; this, combined with tiny TSOT25 or TSOT26 packages, ensures a small circuit-board footprint in end-equipment such as TVs, monitors, set-top boxes, routers, notebook PCs and security systems. A 100% duty cycle allows the devices to work with the lowest VIN and a low quiescent current of just 90µA helps conserve the life of battery-powered equipment. The devices also feature an integrated soft-start that prevents damage as the output switches turn on while integrated over-current and over-temperature protection (OCP and OTP) protect both the system and the IC from damage under fault conditions.
