Microchip Voltage Supervisor Power On Reset Circuit 1 Supervisor 3-Pin 2.6 V SOT-23 MIC803-26D2VM3-TR

Microchip MIC803-26D2VM3-TR voltage supervisor is a power on reset circuit designed for accurate monitoring of power supply voltage in microprocessor-based systems. It features a 3-pin SOT-23 package and a reset threshold voltage of 2.6 V, providing reliable reset signal generation when the supply voltage falls below the preset value.

The device includes an open-drain RESET output that remains valid with supply voltage as low as 1 V, ensuring reset integrity during brown-out conditions. It offers three selectable reset timeout periods: 20 ms, 140 ms, and 1120 ms, catering to diverse application requirements.

Typical supply current is very low, around 4.5 microamperes at 3.6 volts, making it highly efficient for battery-powered and portable applications. The monitored voltage is nominally 1 V, and the device supports input supply voltages from 1 V up to 5.5 V.

The supervisor operates over a wide temperature range from -40°C to 125°C junction temperature, suitable for a broad range of industrial and commercial environments. It does not include a watchdog timer or manual reset capability. This part is RoHS compliant, meeting modern environmental and safety standards.

Its compact SOT-23 form factor, measuring 2.9 mm in width and 2.3 mm in length, makes it easy to integrate into space-constrained PCB layouts. The MIC803 series is trusted for stable power fail detection and reset generation in embedded systems, instrumentation, industrial controls, and communication devices.

This voltage supervisor is ideal for applications requiring a simple and effective power monitoring solution, ensuring system stability by preventing microprocessor malfunctions caused by voltage dips below the reset threshold.
