Microchip Voltage Supervisor 2.9V Reset Threshold SOT-23-5

The Microchip Voltage Supervisor SOT-23-5 offers a nominal 2.9 V reset threshold to keep microcontrollers in reset until the system voltage has stabilised at a safe operating level. It helps protect against brown-out conditions when the supply voltage falls below the set threshold, and has a low typical supply current of 1 µA.

Key Features

• Nominal reset threshold voltage of 2.9 V
• Monitors a single supply voltage within the range of 1 V to 5.5 V
• Low supply current of 1 µA typical (10 µA maximum)
• Reset delay time-out options of 1.4 ms, 30 ms, 200 ms or 1.6 s (typical)
• Watchdog timer input with time-out options of 6.3 ms, 102 ms, 1.6 s or 25.6 s (typical)
• Manual reset (MR) input, active-low
• Push-pull reset outputs, available in active-high or active-low configurations
• Single and complementary reset outputs

Applications

The supervisor is suited to power-sensitive designs and to automotive and industrial applications, given its AEC-Q100 qualification. It resets the microcontroller during power-loss events, and its reset delay and watchdog time-out options allow the response to be tailored to system requirements.

Package and Handling

The device is supplied in a surface-mount SOT-23 package with five pins and operates over a temperature range of -40°C to +125°C. It is ESD sensitive, so proper handling precautions are necessary during assembly and use.

Choose the Microchip Voltage Supervisor SOT-23-5 where reliable reset control and voltage monitoring are required in a compact, power-sensitive design.
