Description
The CF12V2T4R0 is a low-power CMOS voltage threshold detector designed for supervision of microcontroller/microprocessor systems. It detects power-on/off conditions and generates a system reset pulse. It also provides a power fail (POWF) output activated at a precise factory-programmed trip point. With a built-in delay determined by an external capacitor, it offers a variable reset delay. Additionally, it features a second comparator for a second monitoring point and provides advance warning of power fail. The CF12V2T4R0 operates in a temperature range of -40 to +85 °C.
Specifications and features
- Very low current consumption, typically 10 µA
- 10 factory-programmed threshold voltages available, covering trip voltages from 4.75 to 2.55 V
- ±50 mV trip point accuracy over full temperature range
- Variable reset delay
- Reset pulse polarity selection
- Defined outputs at 0.6 V (typ.)
- Comparator for second level detection (e.g. overvoltage detection)Application Scenarios
The CF12V2T4R0 is suitable for use in microcontroller/microprocessor systems. It can be used for power-on/off detection, system reset pulse generation, power fail detection, and advance warning of power fail.
