Vcc Undervoltage LockOut (UVLO)
The device incorporates an Undervoltage Lockout block
to prevent the circuit from operating when Vcc is too low
in order to ensure a proper operation. An UVLO
comparator monitors Vcc pin voltage to allow the NCP1654
to operate when Vcc exceeds 10.5 V typically. The
comparator incorporates some hysteresis (1.5 V) to prevent
erratic operation as the Vcc crosses the threshold. When Vcc
goes below the UVLO comparator lower threshold (9 V
typically), the circuit turns off. It is illustrated in Figure 47.
After startup, the operating range is between 9 V and 20 V.

Thermal Shutdown
An internal thermal circuitry disables the circuit gate
drive and then keeps the power switch off when the junction
temperature exceeds 150
°C. The output stage is then
enabled once the temperature drops below typically 120
(i.e., 30
°C hysteresis). The thermal shutdown is provided
to prevent possible device failures that could result from an
accidental overheating.
