The MCP809 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. MCP809 has a CMOS push-pull output with active low reset and is available in a choice of seven different trip voltages. It operates over the extended industrial temperature range (-40°C/+85°C). MCP809 is available in a SOT23-3 package.
Additional Features
Holds microcontroller in reset until supply voltage reaches stable operating voltage
Resets microcontroller during power loss
Precision monitoring of 3V, 3.3V and 5V systems
Active low RESET pin (MCP809) or active high RESET (MCP810)
Push-pull output
Holds RESET for 350ms (typical)
RESET to VDD = 1.0V
Accuracy of +(-)125mV for 5V systems and +(-)75mV for 3V systems over temperature
45uA typical operating current
Temp range:
Industrial (I): -40C to +85C
