STMicroelectronics | STM6315MDW13F

The STM6315MDW13F is a 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.

Features:

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