Describe：

6-pin microprocessor reset monitoring circuit (µP Supervisory Circuit), integrated power failure comparator (Power-Fail Comparator). This device is a high-precision voltage monitoring chip used to monitor the power voltage in digital systems. It provides a reset signal to the microprocessor when the system is powered on, powered off, or under voltage. The built-in factory pre-adjusted reset threshold voltage is 3.08V, and it has a 1.25V threshold detector for power failure alarms or low battery detection. The output is low-level valid and open-drain output, with a minimum reset timeout of 100ms. It supports a wide operating voltage range of 1V to 5.5V, and the chip can still ensure a valid reset output when Vcc is as low as 1V. It is packaged in a miniature 6-pin SOT-23 package, with a working temperature range of -40°C to +125°C.

Features ：

• Basic parameters: One monitoring voltage channel, chip type: Simple Reset/Power-On Reset, threshold voltage: 3.08V

• Output type: Open Drain or Open Collector, reset with low-level active (Active Low), requires an external pull-up resistor (typical value 10kΩ)

• Reset timeout: 100ms (minimum value), typical reset pulse width is 180ms

• Power Failure Comparator: Integrated 1.25V threshold detector (PFI pin), can be used for power failure alarm, low battery detection or monitoring of another power supply.

• Manual reset input: The MR pin supports external button reset, with an internal anti-shaking circuit, and triggers with a valid low level.

• Wide operating voltage range: 1.0V to 5.5V. The reset output logic remains valid even when Vcc is as low as 1V.
