Summary description
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
V
above the preset threshold for a minimum period of time (t
reset input (MR). The open drain RST output can be pulled up to a voltage higher than V
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.
