3A MOTOR DRIVER WITH BRAKE FUNCTION

· Detailed explanation

The output current is detected by monitoring the VBE from each output transistor. One detection circuit

connects to one of the output transistors and leads to the short-circuit protection circuit. When a current

exceeding the ISD detection current flows through one of the four output transistors, the short-circuit

protection circuit is activated. This circuit contains a timer. When overcurrent condition continues for 20μs

(typically) , the protection circuit places the output in high-impedance mode and, 80μs (typically) later,

returns the IC to ON mode. The switching-waveform output is repeated until overcurrent condition is no

longer present.
