V770 2.0 mp HBridge Driver This automotive grade HBridge driver provides a flexible means for controlling loads requiring bidirectional drive currents.

1 V mp HBridge Driver This automotive grade HBridge 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 V770 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 V770 is produced using ON Semiconductor's POWERSSE BCD technology.

When the undervoltage lockout threshold is exceeded, the outputs will reflect the input states. Outputs change to HIZ whenever an undervoltage, overvoltage or thermal shutdown fault is detected. Normal operation will resume when faults are resolved. FULT IN Overcurrent Protection Current is monitored continuously in each switch of each half bridge when the input is in a high state thus protecting each switch from faults due to short to, short to V BT or shorted load conditions. Only the affected halfbridge is disabled for short to V BT or short to faults. 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 HIZ and the FULT output to latch low until the next transition occurs on either the input related to the faulted output or the input is brought low then high again. This method of protection provides current limiting on a cyclebycycle 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 V770. V CC Controller Figure 2. pplication Diagram 4
