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 V
cc
pin voltage to allow the NCP1654
to operate when V
cc
exceeds 10.5 V typically. The
comparator incorporates some hysteresis (1.5 V) to prevent
erratic operation as the V
cc
crosses the threshold. When V
cc
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癈. The output stage is then
enabled once the temperature drops below typically 120癈
(i.e., 30癈 hysteresis). The thermal shutdown is provided
to prevent possible device failures that could result from an
accidental overheating.
