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 mA 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.

2. Designed to meet these characteristics over the stated voltage and temperature recommended operating ranges, though may not be 100%
parametrically tested in production.
3. Operation is guaranteed down to VB = 6.0 V. Electrical characteristics may be outside the limits at that voltage.
4. See Figures 2 and 3; VB = 14 V, R = 100 W.
5. CT must remain in this range to guarantee proper operation, and to ensure part integrity, during hard short conditions.
6. See Figures 2 and 4; VB = 14 V, R = 100 W.
7. Guaranteed by design.
8. Consult factory for no overvoltage detection or lower overvoltage detection threshold options.
