Three-phase brush-less motor driver works as much as 140V

Infineon 6ED2742S01Q dc motor driver

Referred to as 6ED2742S01Q, it’s designed to drive six exterior n-channel mosfets utilizing bootstrapping for the higher three, however it unusually features a low-power cost pump to permit 100% obligation cycle high-side operation. For conventional bootstrapped operation, three diodes are built-in to keep away from the necessity for exterior diodes.

Its gate drives supply 1A and sink 2A, and have unbiased under-voltage lock-out (UVLO) for each high-side and low-side gate drives.

Whereas the facility enter could be wherever between 10.8 and 140V, the bootstrap terminal is specified as much as 160V.

Propagation delay is 100ns, and there’s a minimal useless time of 100ns with built-in delay matching.

along with UVLO, safety options embrace: over-current safety with configurable threshold, fault communication and automated fault restoration.

A present sense amplifier with selectable achieve is offered not just for output safety however for exterior use. It operates together with an exterior low-side sequence resistor which could be as little as 10mΩ and features a deliberate voltage offset ~150mV) ensures the measured worth stays optimistic (doesn’t go unfavourable in common operation). A management sign permits this offset to be learn externally for subtraction elsewhere.

inputs are 3.3 and 5V appropriate, and the IC is protected in opposition to 2kV human-body mannequin ESD.

Packaging is 5 x 5mm uncovered pad QFN32 and operation is over -40 to 125°C.

Functions are foreseen in forklifts, warehouse robots, hand energy instruments, drones, and battery-operated family home equipment, in addition to small automobiles that don’t require automotive qualification.
