In H-Bridge configuration it is not advisable to short the motor to V
damage the 33486A. The current recirculation in the low-side MOSFET is a preferred solution, with IN1 = 0 and IN2 = 0.
Once the overvoltage condition or undervoltage condition is removed, the H-Bridge recovers its normal operation mode.
When the thermal shutdown is reached on one of the high-side MOSFETs, both high sides are turned off with the motor tied to ground.
When the overtemperature condition is finished, the H-Bridge recovers it previous normal operation mode.
The high-side MOSFET HSn that experienced an overcurrent is latched off. The corresponding output OUTn is open. Once the high-
side overcurrent condition is removed, the input INn must be reset in order to recover the normal operation mode.
When a short to V
low-side overcurrent is removed, the input INn of the output that experienced the fault must be reset in order to recover the normal
operation mode.
OUT2 are both put in high impedance. IN2 must be reset to recover normal mode.
