Data Sheet - Detailed Description

Power-On Reset

The AS1325 provides a power-on reset output (RESETN) that goes high-impedance when the output reaches 90% of

its regulation point. RESETN goes low when the output is below 90% of the regulation point. A 100kΩ to 1MΩ pullup

resistor between pin RESETN and pin OUT can provide a microprocessor logic control signal.

Note: Connect pin RESETN to GND when the power-on reset feature is not used.

Antiringing Control

If the inductor current falls to zero, an internal 100Ω (typ) antiringing switch is connected from LX to BATT to minimize

EMI. The antiringing control can be deactivated by not connecting the pin BATT. The device is supplied by the pin OUT

- no supply current flows into pin BATT.
