NCV7702B

1 A Dual H-Bridge Driver

This dual full-bridge driver IC is intended for 14 V automotive

stepper and DC motor applications. Its four half-bridge outputs are

configured as two channels and are programmed by six TTL

compatible inputs, allowing flexible control of bridge operation. The

device operates in standby mode, run mode, or brake mode and

typically consumes less than 1

while in standby. In run mode,

each half-bridge output can deliver load current in either direction.

Brake mode activates the low side transistors or high side transistors

at the selected outputs. On-chip recirculation diodes are provided,

and the IC has multiple fault protection modes. Overcurrent

detection protects against shorted loads between outputs and shorts

to supply or ground at each output. An overcurrent fault condition

activates an internal timer, which modulates faulted outputs at low

duty cycle. An overcurrent condition in one channel does not affect

operation in the other. Overvoltage and overtemperature detection

are also provided, and turn off all bridge outputs during these fault

conditions. Recovery from all fault conditions is automatic; the IC

will resume normal operation in its previously selected mode upon

fault resolution. Diagnostic ability is provided by two open-collector

STATUS outputs which report the fault status of each channel

independently during overcurrent faults, and together during

overvoltage or overtemperature faults.
