• Manufacturer Part Number: MC33886
• Description: 5.0 A H BRIDGE
• Manufacturer: Motorola

The tri-state conditions and the fault status are reset using D1 or
X = High or Low, and Z = High impedance (all output power transistors are switched off).

28.
In the case of an undervoltage condition, the outputs tri-state and the fault status is set logic Low. Upon undervoltage recovery, fault status
is reset automatically or automatically cleared and the outputs are restored to their original operating condition.
When a short circuit or overtemperature condition is detected, the power outputs are tri-state latched-OFF independent of the input signals
and the fault status flag is set logic Low.
