Description
The Microchip Technology Inc.
MCP120/130 is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized.
Features
- Holds microcontroller in reset until supply voltage reaches stable operating level.
- Resets microcontroller during power loss.
- Precision monitoring of 3V, 3.3V and 5V systems.
- 7 voltage trip points available.
- Active low RESET pin.
- Open drain output.
- Internal pull-up resistor (5 kΩ) for MCP130.
- Holds RESET for 350 ms (typical).
- RESET to VCC = 1.0V.
- Accuracy of ±125 mV for 5V systems and ±75 mV for 3V systems.
