Microchip MCP120T-300I/TT

简单复位/加电复位2.925V1

Overview

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. 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 open drain outputs. The MCP130 has an internal 5 kΩ pullup resistor. Both devices have active low RESET pins. The MCP120/130 will assert the RESET signal whenever the voltage on the VDD pin is below the trip-point voltage.

• 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 over temperature • 45 μA typical operating current • Temperature range: - Industrial (I): -40°C to +85°C
