The MCP131 is a micropower voltage supervisor from Microchip Technology, Inc., designed for applications requiring low power consumption. It operates with a maximum supply current of 1.75 ¬µA and supports a wide operating voltage range of 1.0V to 5.5V. The device features an active-low open-drain output with an internal pull-up resistor, making it suitable for interfacing with various microcontrollers. The MCP131 includes a reset delay timer of approximately 120 ms and offers multiple precision monitoring trip points at 1.90V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V, and 4.63V, with a trip point accuracy of ¬±1.5%. It is available in compact SOT-23, SC70, and TO-92 packages, and operates effectively across an extended temperature range of -40¬8C to +125¬8C. This device is particularly useful in critical power-monitoring applications, including portable battery-powered equipment and intelligent instruments.
The MCP131 Series, of CMOS voltage supervisors, are well suited for portable and consumer electrics applications due to the extremely low 1uA 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.
