Integrated Circuit For Standby Power-Supply Control

Toshiba 

TA1307P

In addition, there is a function below as a PROTECT circuits.

A terminal 5 (OCL) detects the overcurrent of MOSFET connected to the terminal 7 (pulse out), and output Pulse

is made to compulsion low at the time of an overcurrent.

Output pulse will be made to compulsion low, if it flows into a terminal 7 (pulse out) and there is always 40 mA or

more of current.

Output pulse will be made to compulsion low, if the supply voltage of a terminal 1 (VCC) becomes more than

12 V.(OVLO)

Circuit operation start of the UVLO function is carried out more than by 7 V, and it carries out a circuit operation

stop less than 5 V.
