Note:
*
The dead time for the length current prevention in positive and the reversing switch is set by
internal control IC. The set point in internal IC at the dead time is 20µs (typical).
Please take into account the dead time and consider the load conditions when you use the IC.

Note:
*
1:
The standard value of I
OCP
is assumed to be a value by which the output of each Power MOS FET cuts off. When the
protection circuit of OCP and TSD operates, Power MOS FETs keeps cutoff. When a signal (5V: H
➞
0V: L) is input to the
terminal PWM, the cutoff operation will be released. Moreover, three minutes (Ta=25ºC, f
PWM
=10kHz, V
M
=14V) are assumed
to be max at the overcurrent state continuance time in the V
M
operation and the ground of output terminal (OUT1, OUT2).
It is not the one to assure the operation including reliability in the state that the short-circuit continues for a long time.
