Application Information
1. Under Voltage Lockout (UVLO)
2. Current Sensing Circuit
The peak current, I
For example, if a required maximum current, I
3. Thermal Shutdown (Tsd)
When the chip, temperature rises up to 150 C, the thermal shutdown (TSD) circuit is activated and the output driver turn off,
and then turn on again at 125 C.
