Allegro MicroSystems, LLC Announces New Low Voltage Bipolar Stepper or Dual DC Motor Driver IC

Allegro MicroSystems, LLC announced a new low voltage bipolar stepper or dual DC motor driver IC. The A3916 device was designed for pulse-width-modulated (PWM) control of low-voltage stepper motors or dual DC motors and is capable of output currents up to 1 A per channel and operating voltages from 2.7 to 15 V. Allegro’s new motor driver IC is targeted at the office and industrial automation, point of sale, 3 D printing, medical, CCTV, toy markets, and other applications that run off single, Li-ion cell or 3 AA batteries. The A3916 integrates all motor control including a fixed off-time PWM regulator that sets a peak current in motor winding based on the selection of a low value a current sense resistor. A single supply eliminates the need for external LDO and an integrated charge pump requires only one external capacitor. Output diagnostic is provided by an active low fault output that notifies the user of a TSD or overcurrent protection event. Two package options are offered, a low-profile 3 × 3 mm 16-terminal QFN (suffix “ES”) and a drop-in replacement for the A3916 in a low-profile 4 × 4 mm 20-terminal QFN (suffixes “ES, -1”), both products have an exposed power tab for enhanced thermal dissipation.

Allegro MicroSystems, LLC Announces Dual Die Highly Programmable Linear Hall Sensor IC

Allegro MicroSystems, LLC Announced Dual Die Highly Programmable Linear Hall Sensor IC. Dual-Die Programmable Linear Hall IC with Advanced Diagnostics for Safety-Critical Applications The A1346 is the ideal solution for safety-critical applications. It incorporates full die redundancy with the added benefits of advanced diagnostics. The combination of these two features allow for a higher level of diagnostics without interruption to the application (where diagnostics would otherwise render a die temporarily nonresponsive). This combination also allows the controller to know which die to trust when the output of the die do not agree. The A1346 device has dual high-precision, programmable Hall-effect linear sensor integrated circuits (IC) with open-drain outputs, for both automotive and nonautomotive applications. The signal paths of the A1346 provides flexibility through external programming that allows the generation of accurate and customized outputs from an input magnetic signal. The A1346 is an especially configurable and robust solution for the most demanding linear field sensor applications. The BiCMOS, monolithic integrated circuits incorporate on each SoC: a Hall sensing element, precision temperature-compensating circuitry to reduce the intrinsic sensitivity and offset drift of the Hall element, a small-signal high-gain amplifier, proprietary dynamic offset cancellation circuits, advanced output linearization circuitry, and advanced diagnostic detection. The A1346 provides an unmatched level of customer reprogrammable options. A key feature of the A1346 is its ability to produce a highly linear device output for nonlinear input magnetic fields. To achieve this, the device features 16-segment customer programmable linearization, where a unique linearization coefficient factor is applied to each segment. Linearization coefficients are stored in a lookup table in EEPROM. The A1346 contains two proprietary SENT protocols in addition to SAEJ2716: SSENT and ASENT. Both protocols enable the user to attach up to 4 devices on one SENT line to reduce system costs. SSENT provides sequential access to the sensors connected to the same line. SSENT provides a very low overhead method to maximize the sensor bandwidth on this single SENT line, minimizing impact on system performance. ASENT provides random access to all the sensors on the common SENT line. Both protocols allow individual sensors on the same line to enter diagnostic mode while the other sensors continue to respond to queries, allowing for high diagnostic coverage while maintaining 100% availability of the sensor solution. The A1346 is available in a surface-mount, lead (Pb) free 14-pin TSSOP package (LE suffix), with 100% matte-tin leadframe plating.

Allegro MicroSystems, LLC Announces New Programmable Hall-Effect Linear Sensor IC

Allegro MicroSystems, LLC has announced a new programmable Hall-effect linear sensor integrated circuit, or IC, with an open-drain output, for both automotive and non-automotive applications. The signal path of Allegro's A1342 provides flexibility through external programming that allows the generation of an accurate and customized output from an input magnetic signal. This new device is an especially configurable and robust solution for the most demanding linear field sensor IC applications. The BiCMOS, monolithic IC incorporates a Hall sensing element, precision temperature-compensating circuitry to reduce the intrinsic sensitivity and offset drift of the Hall element, a small-signal high-gain amplifier, and proprietary dynamic offset cancellation circuits, advanced output linearization circuitry, and advanced diagnostics. Allegro's A1342 provides an unmatched level of customer-programmable options. A key feature of the A1342 is its ability to produce a highly linear device output for non-linear input magnetic fields. To achieve this, the device features 16-segment customer-programmable linearization, where a unique linearization coefficient factor is applied to each segment. Linearization coefficients are stored in a look-up table in EEPROM. This new device has two configurable output options: SENT or PWM. In addition to SAEJ2716, the IC includes two additional proprietary SENT options: SSENT and ASENT. Both protocols enable bus configurations with up to four devices on one SENT line to reduce system costs. SSENT provides sequential access to the sensors connected to the same line. SSENT provides a very low overhead method to maximize the sensor bandwidth on this single SENT line, minimizing impact on system performance. ASENT provides random access to all the sensors on the common SENT line.Both protocols allow individual sensors on the same line to enter diagnostic mode while the other sensors continue to respond to queries, allowing for the highest diagnostic coverage while maintaining 100% availability of the sensor solution. The A1342 is available in a through-hole, lead (Pb) free 3-pin SIP package (UC suffix), with 100% matt-tin leadframe plating. The UC package includes integrated capacitors for improved ESD performance and to enable PCB-less designs.
