概述
R3121 is the 36 V Maximum Input Voltage Detector (Maximum Rating: 50 V). Selectable options of VDD Pin Detection Type (R3121NxxxA), SENSE Pin Detection Type (R3121NxxxE) and VDD Pin Detection without Hysteresis Type (R3121NxxxG), depending on the system configurations.
特点
- Highly accurate voltage detection with detector threshold accuracy ±1.5% (Ta = 25°C)
- Selectable options of VDD Pin Detection, SENSE Pin Detection and VDD Pin Detection without Hysteresis
- Adjustment of the release delay time (Power-on Reset Time) by connecting external capacitors
- Reduction of mounting area by using compact package of SOT-23-6
