FULL-BRIDGE POWER MOSFET CONTROLLER
— For Automotive Applications
3940
The A3940KLP and A3940KLW are designed specifically for
automotive applications that require high-power motors. Each provides
four high-current gate drive outputs capable of driving a wide range of
n-channel power MOSFETs in a full-bridge configuration.
Bootstrap capacitors are utilized to provide the above-battery
supply voltage required for n-channel FETs. An internal charge pump
for the high side allows for dc (100% duty cycle) operation of the
bridge.
Protection features include supply under/overvoltage, thermal
shutdown, and motor lead short-to-battery and short-to-ground fault
notification, and a programmable dead-time adjustment for cross-
conduction prevention.
The
overvoltage trip point is user adjustable.
The A3940 is supplied in a choice of two power packages, a 28-
lead TSSOP with an exposed thermal pad (suffix LP), and a 28-lead
wide-body SOIC (suffix LW).

thermal shutdown circuitry. These conditions
can be tolerated, but should be avoided.
