Thermal Shut-Down circuit (TSD)

Latch return TSD = 160°C (typ.) (Note)

(1)When recovery signal is outputted after the temperature falls lower than recovery temperature (90°C (typ.) in

the below figure (Note)).

The operation returns by programming the STBY as H → L → H shown in above figure or turning on

power supply and turning on UVLO function.

(2)When recovery signal is outputted before the temperature falls lower than the recovery temperature (90°C(typ.)

in below figure (Note)).

If STBY is programmed H → L → H shown in the above figure before the temperature falls lower

than the recovery temperature (90°C(typ.) in the above figure (Note)), the operation does not return.

Note: Pre-shipment testing is not performed.

STBY = L: TSD is not enabled.
