About This Product

■Summary

R3121 is a voltage detector with a maximum input of 36V (absolute maximum rating: 50V). VDD terminal detection type (R3121NxxxA), SENSE terminal detection type (R3121NxxxE), and VDD terminal detection type without hysteresis (R3121NxxxG) can be selected according to the system configuration.

■Features

・Detection voltage accuracy is ±1.5% (Ta=25℃), meeting high-precision voltage detection requirements ・VDD terminal detection, SENSE terminal detection, lineup with/without hysteresis to meet various system requirements ・Release delay time (power-on reset time) can be set using an external capacitor - Small package (SOT-23-6) allows for reduction of mounting area
