MCP102/103/121/131

Micropower Voltage Supervisors

Features:

General Description:

The MCP102/103/121/131 devices are voltage

supervisor devices designed to keep a microcontroller

in reset until the system voltage has reached and

stabilized at the proper level for reliable system

operation. Table 1 shows the available features for

these devices.

• Ultra-Low Supply Current: 1.75 µA

(steady-state maximum)

•

Precision Monitoring Options of:

- 1.90V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V and

4.63V

• Resets Microcontroller in a Power-Loss Event

• RST Pin (active-low):

Package Types

- MCP121: Active-low, Open-drain

SOT-23/SC70

TO-92

- MCP131: Active-low, Open-drain with Inter-

nal Pull-up Resistor

- MCP102 and MCP103: Active-low, Push-pull

• Reset Delay Timer (120 ms delay, typical)

• Available in SOT-23, TO-92 and SC70 Packages
