STM6315:Open Drain Microprocessor Reset

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
