Microchip | MCP101-300HI/TO

The MCP101 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.

MCP100 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). MCP101 is available in a TO-92 or SOT23-3 packages.

Features:

• Holds microcontroller in reset untill supply voltage reaches stable operating level
• Resets microcontroller during power loss
• Precision monitoring of 3 V, 3.3 V and 5 V systems
• 7 voltage trip points available
• Active low RESET(bar) pin (MCP100) or active high RESET(MCP100)
• Push-pull output
• Holds RESET(bar)/RESET for 350 ms (typical)
• RESET(bar)/RESET to Vdd = 1.0 V
• Accuracy of ±125 mV for 5 V systems and ±75 mV for 3 V systems over temperature
• 45 µA typical operating current
• Temperature range:
• Industrial (I): -40ºC to +85ºC
