Operating frequencies up to a high 600 kHz
Built-in pre-driver circuit for driving power MOS FET
Built-in timer latch over-current protection function (HA16107)
The OCL enables intermittent operation by an ON/OFF timer for prevention of secondary overcurrent.
(HA16108)
The UVL function (under voltage lockout) is applied to both Vin and Vref.
ON/OFF reset: an auto-reset function which is based on the time constant of an external capacitor and
observation of drops in Vin.
Since the over-voltage protection function OVP (the TL pin) only observes voltage drops in Vin, it is
possible to use the OVP and ON/OFF pin for independent purposes.
Built-in 34 V Zener diode between Vin and ground.
