Microchip Voltage Supervisor 2.9V Reset Threshold SOT-23-5
Microchip voltage supervisor in SOT-23-5 with 2.9 V reset threshold, 1 µA typical supply current and -40°C to +125°C operating range.
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.
