onsemi Voltage Supervisor Micropower Under Voltage Sensing Circuit 3-Pin TO-92 Package MC33164P-3G

onsemi MC33164P-3G Voltage Supervisor is a robust micropower under voltage sensing circuit designed for power management and monitoring applications. It operates with a single supervisor configuration and is housed in a compact 3-pin TO-92 through-hole package providing ease of assembly onto printed circuit boards.

This device monitors a 3 V power supply with a reset threshold voltage set at 2.8 V, ensuring precise and reliable power supervision. The temperature compensated reference and precise comparator thresholds guarantee consistent performance across a wide temperature range from -40°C up to 125°C, making it suitable for industrial, automotive, and consumer electronic applications.

Featuring an open collector output driver, this voltage supervisor can sink currents exceeding 6 mA, providing effective reset signaling to connected systems. It includes an internal clamp diode that helps in discharging delay capacitors to prevent erratic resets. Additionally, its extremely low standby current consumption of as low as 9 μA optimizes power efficiency during non-operational modes.

The MC33164P-3G accepts a supply voltage range from 1 V to a maximum of 10 V. Its guaranteed operation at low input voltages as low as 1 V and the temperature compensated reference provide stable and accurate supervision for critical system voltages. This component is ideal for use in industrial controls, automotive systems, telecommunications equipment, and power supplies where undervoltage supervision is critical.
