Diodes Incorporated Introduces Single-Channel Load Switch Designed to Operate from 4.5V Up to 12V with A Near-Zero Quiescent Supply Current
Apr 23 15
Diodes Incorporated announced that it has introduced a single-channel load switch designed to operate from 4.5V up to 12V with a near-zero quiescent supply current that makes it suitable for use in battery-powered netbooks, tablets and e-Readers. The AP22850 can handle power up/down sequencing with load currents up to 8A and adjustable start-up and discharge rates. It is offered in the space-saving, thermally efficient 2mm x 2mm x 0.8mm W-DFN2020-8 package, maximizing available board space. These functions and performance are delivered cost-effectively by the AP22850, which is based on a P-channel MOSFET that has a low typical RDS(ON) of 20mÎ©. The device can handle inputs up to 12V with a maximum output current of 8A but with a quiescent (no-load) current of just 1.2nA. The AP22850 does not require an external gate pull-up resistor and integrates circuitry to suppress fast input transients from coupling to the output; these features contribute to reduced BOM costs and board area savings.
Diodes Incorporated Introduces AP431i
Apr 21 15
Diodes Incorporated introduced the AP431i. This adjustable shunt regulator features a 50µA minimum cathode current that is significantly lower than equivalent industry-standard 431 devices. This enables manufacturers of switch-mode power supplies to target applications that require very low power dissipation, particularly 12V/19V adaptors/chargers, but also TVs and monitors where standby power consumption is of great importance. With reliable thermal stability over its full operating range, the AP431i three-terminal adjustable-shunt regulator features fast turn-on characteristics, a low temperature coefficient and low output impedance. The AP431i has the same electrical specifications as a standard 431, while having an advantage of being able to regulate with a low minimum cathode current, typically 50µA. This key differentiator makes it well-suited as a Zener diode substitute in switch-mode power supplies (SMPS). The output voltage of AP431i can be set to any value between VREF (2.5V) and the corresponding maximum cathode voltage (36V). Two grades of initial voltage tolerance are offered, 0.5% and 1%, with three package options available: TO-92 (ammo-pack), SOT-23 and SOT-89. These packages are fully RoHS compliant and totally lead-, halogen- and antimony-free 'green' devices.
Diodes Incorporated Announces Resignation of Chieh Chang as Vice President and Senior General Manager of Worldwide Analog Products
Apr 2 15
Effective as of March 31, 2015, Chieh Chang, the former Chief Executive Officer of BCD Semiconductor Manufacturing Limited (BCD), which was acquired by Diodes Incorporated on March 5, 2013, resigned as the Vice President, Senior General Manager, Worldwide Analog Products of the company. Mr. Chang resigned upon the completion of his two year paid retention period following the acquisition of BCD.
Diodes Incorporated Introduces AZV3001
Mar 25 15
Diodes Incorporated introduced the AZV3001. This new generation single-channel comparator has been specifically developed for use in battery-powered equipment that needs to operate at low voltage. The single-channel consumes only 6¼ and provides guaranteed operation from 1.6V up to 5.5V, making it well-suited for use in systems with nominal supplies of 1.8V, 3.0V or 5.0V, such as mobile phones, tablets and notebook computers, where it delivers superior performance and helps extend battery life. The comparator features internal hysteresis in order to provide immunity to undesirable small voltage fluctuations, and uses a complementary output stage, comprising P- and N-channel MOSFETS, in order to drive outputs with a full rail-to-rail voltage swing. Miniaturized package options help reduce PCB board space: the AZV3001 is offered in a 6-pin X2-DFN1410-6 package and the dual-channel AZV3002, available later this year, in an 8-pin U-FLGA1616-8 package. With a low propagation delay of 0.8µs, a low input bias current of 1pA and no risk of phase inversion when the input is overdriven, these comparators offer embedded system design engineers a general-purpose solution to almost all low-voltage portable device requirements.
Diodes Incorporated Introduces the ZXTR2105F
Mar 12 15
Diodes Incorporated introduced the ZXTR2105F. This regulator monolithically integrates a transistor, Zener diode and resistor to provide a 5V 15mA output from inputs up to 60V. Offered in a small SOT-23 package, the ZXTR2105F transistor reduces component count and minimizes PCB area in microcontroller applications, such as DC cooling fans for PCs and servers, as well motor drive, blowers and sensor applications in industrial and automotive market segments. The ZXTR2105F is designed to replace three discrete components, and when typically used to produce a stable supply of between 4.7V and 5.3V from 12V or 24V inputs, not only minimizes the solution footprint but also increases system power density and reliability. The device's 60V maximum input rating ensures sufficient headroom in the event of transient over-voltage conditions, while its excellent line and load regulation safeguards continuous operation by ensuring transient voltage drops cannot cause latch-up, which further contributes to system reliability.
