Microchip | MCP131T-270E/LB

The MCP131 Series, of CMOS voltage supervisors, are well suited for portable and consumer electrics applications due to the extremely low 1 uA operating current and small surface-mount packaging.

These devices are designed to hold the microcontroller in reset until the supply voltage reaches a predetermined operating level. These devices also protect against brownout conditions that occur as a result of the supply voltage dropping below a tolerable level.

Features:

• Ultra low supply current: 1.75 μA (steady-state max.)
• Precision monitoring options of:
• 1.90 V, 2.32 V, 2.63 V, 2.93 V, 3.08 V, 4.38 V and 4.63 V
• Resets microcontroller in a power-loss event
• RST pin (Active-low):
• MCP121: Active-low, open-drain
• MCP131: Active-low, open-drain with internal pull-up resistor
• MCP102 and MCP103: Active-low, push-pull
• Reset Delay Timer (120 ms delay, typ.)
• Available in SOT23-3, TO-92 and SC-70 packages
• Temperature Range:
• Extended: -40°C to +125°C (except MCP1XX-195)
• Industrial: -40°C to +85°C (MCP1XX-195 only)
• Pb-free devices

Applications:

• Critical Microcontroller and Microprocessor Power-monitoring Applications
• Computers
• Intelligent Instruments
• Portable Battery-powered Equipment
