Product Introduction
The MCP809/810 is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level. Both devices are available with a choice of seven different trip voltages and both have push-pull outputs. The MCP809 has a low active RESET pin and the MCP810 has a high active RESET pin. The MCP809/810 will assert the RESET/RESET signal whenever the voltage on the VDD pin is below the trip-point voltage.
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 (MCP809) or active high RESET (MCP810)
- Push-pull output
- Holds RESET/RESET for 350 ms (typical)
- RESET/RESET to VDD = 1.0V
- Accuracy of ±125 mV for 5V systems and ±75 mV for 3V systems over temperature
- 45 μA typical operating current
- Temperature range: - Industrial (I): -40°C to +85°C
