(7) Output short-circuit protection
To protect IC from damage due to short-circuit of the output caused by lightening or ground fault, the output
short-circuit protection circuit to put the output in the OFF mode is incorporated.
7-1) Protective function operation (Latch method)
When detecting the output short-circuit state, the short-circuit protection circuit is activated.
When short-circuit state is detected ≈ 4μs (count by the internal timer), detected output is OFF at the time.
Then, when the output exceeds the timer latch time counted by the internal counter, the output is ON. Still, the short
circuit state is detected, the IC switches all output to stand-by mode and keep the state.
This state is released by setting PS = Low
(8) Abnormal condition warning output pin
EMO, warning output pin of thermal shutdown circuit and the output short-circuit protection circuit, is an open-drain
output. EMO outputs ON when output short-circuit is detected.
When detecting the output overdrive, the EMO outputs ON. If the junction temperature goes down at the time, EMO
outputs OFF automatically.
(9) Recommended power-on sequence
Provide a wait time of 10μs or more after VCC power supply rises before supplying VM power supply.
Provide a wait time of 10μs or more after VM power supply raises before setting the PS pin High.
VCC
VM
PS
The above power-on sequence is only a recommendation, and there are no risks of damage or over current to the IC
even if this sequence is not followed.
