Description

The UTM4953-S08-R is an electronic component model in the product category of IC Chips. It is a family of ultra-low-power battery monitors with an integrated microprocessor (µP) supervisor. The battery monitors have options for single or dual low-battery output, which can be used to signal when the battery is OK, low, or dead. They also have an independent µP supervisor that monitors VCC and provides an active-low reset output. No external components are required for this model.
