When the IC junction temperature reaches the specified value and the TSD circuit is activated, the internal
reset circuit turns output off. The TSD activation temperature can be set within the range from 130°C (min)
to 170°C (max). Once the TSD circuit is activated, output is stopped until a pulse (L to H to L) is
subsequently applied to the SLEEP pin. The charge pump is halted while the TSD circuit is active.
The TSD circuit does not include hysteresis. Applying a pulse (L to H to L) to the SLEEP pin deactivates the
circuit.
This circuit is activated when a current pulse exceeding the specified output value is applied for a period of
1/2f
The circuit activates the internal reset circuit to turn output off.
Once it is activated, output is stopped until a pulse (L to H to L) is subsequently applied to the SLEEP pin.
While the ISD circuit is active, the IC is placed in SLEEP mode with the charge pump halted.
