  • The STM6315 Microprocessor Reset Circuit is a low power supervisory device used to monitor power supplies. It performs a single function: asserting a reset signal whenever the VCC supply voltage drops below a preset value and keeping it asserted until VCC has risen above the preset threshold for a minimum period of time (trec). It also provides a manual reset input ( MR ). The open drain RST output can be pulled up to a voltage higher than VCC, but less than 6V.

    The STM6315 comes with standard factory-trimmed reset thresholds of 2.63V, 2.93V, 3.08V, 4.38V, and 4.63V. The STM6315 is available in the SOT143-4 package.

    Key Features

    • Available in SOT143-4 package.
    • Operating temperature: -40 to +125˚C
    • Low supply current of 1.5μA (typ)
    • Guaranteed RST assertion down to VCC= 1.0V
    • ±1.8% reset threshold accuracy (25˚C)
    • Power supply transient immunity
    • Open drain RST output can exceed VCC
