2 A H-Bridge Driver

NCV7701
2.0 Amp H-Bridge Driver
This automotive grade H-Bridge driver provides a flexible means
for controlling loads requiring bidirectional drive currents. Bridge
outputs are protected from overcurrent at each switch and
overtemperature shutdown provides product robustness. The
NCV7701 inputs can be interfaced to a range of voltages, including
vehicle battery voltage. The product features a low quiescent current
mode, allowing unswitched connection to the power source. The
NCV7701 is produced using ON Semiconductor's POWERSENSEt
BCD technology.

Operating Description
During powerup, the outputs are HI-Z regardless of the
input states. When the undervoltage lockout threshold is
exceeded, the outputs will reflect the input states. Outputs
change to HI-Z whenever an undervoltage, overvoltage or
thermal shutdown fault is detected. Normal operation will
resume when faults are resolved.
Overcurrent Protection
Current is monitored continuously in each switch of each
half bridge when the ENA input is in a high state thus
protecting each switch from faults due to short to GND,
short to VBAT or shorted load conditions. Only the affected
half-bridge is disabled for short to VBAT or short to GND
faults. A mask timer is initiated after a fault is detected and
prevents recognition of an overcurrent event until the mask
time expires. Persistence of an overcurrent condition causes
the bridge output to change to HI-Z and the FAULT output
to latch low until the next transition occurs on either the
input related to the faulted output or the ENA input is
brought low then high again. This method of protection
provides current limiting on a cycle-by-cycle basis and
helps allow a stall torque current to be ignored during motor
start. Continued overcurrent may eventually result in
activation of the thermal shutdown circuitry, thus activating
a second level of protection for the NCV7701.
