The XC6118 series is a low power consumption voltage detector with high accuracy detection, manufactured using CMOS process and laser trimming technologies. Since the sense pin is separated from the power supply pin, it allows the IC to monitor the other power supply. The XC6118 can maintain the state of detection even when voltage of the monitored power supply drops to 0V. Moreover, a release delay time can be adjusted by the external capacitor connected to the Cd pin. The VOUT pin is available in both CMOS and N-channel open drain output configurations.
The XC6118 series voltage detector provides high‑accuracy detection (±2 % for VDF ≥ 1.5 V, ±30 mV for VDF < 1.5 V) while consuming only a few microamps. It features a separated sense pin that can monitor an external supply and a Cd pin that allows the release delay to be set with an external capacitor.
Typical applications include microprocessor reset circuitry, charge‑voltage monitoring, memory‑battery backup switching, and power‑failure detection. The device is offered in USP‑4 and SOT‑25 packages and supports both CMOS and N‑channel open‑drain output configurations.
