MCP100 Microcontroller Supervisory and Reset Circuit
The Microchip MCP100 microcontroller supervisory circuit is designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It operates on 1V to 5.5V voltage range. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level. This supervisor has a CMOS Push-Pull output with Active Low reset and is available in a choice of seven different trip voltages.
Holds microcontroller in reset until supply voltage reaches stable operating level Resets microcontroller during power loss Active low RESET pin Push-pull output Holds RESET for 350ms (typical) RESET voltage (Vtrip) range between 4.5V to 4.75V Accuracy of +(-)125mV for 5V systems and +(-)75mV for 3V systems over temp 45uA typical operating current Temperature range between -40°C and 85°C 3-lead TO-92 package with 'H' bondout
