MIC6315 - Open-Drain uP Reset Circuit

General Description

The MIC6315 is an inexpensive reset generator circuit that monitors power supplies in microprocessor-based systems.

The function of this device is to assert a reset if either the power supply drops below a designated reset threshold level or /MR is forced low.

Key Features

  • Precision voltage monitor for 3V, 3.3V, or 5V power supplies.
  • /RESET remains valid with VCC as low as 1V.
  • 5μA supply current.
  • 20ms, 140ms, or 1100ms minimum reset pulse widths available.
  • M.

MIC6315 Open-Drain µP Reset Circuit General Description The MIC6315 is an inexpensive reset generator circuit that monitors power supplies in microprocessor-based systems. The function of this device is to assert a reset if either the power supply drops below a designated reset threshold level or /MR is forced low. Several different reset threshold levels are available to accommodate 3V, 3.3V, or 5V powered systems. The MIC6315 has an active low, open-drain /RESET output. The reset output is guaranteed to remain asserted for a minimum of either 20ms, 140ms, or 1100ms after VCC has risen above the designed reset threshold level. The MIC6315 is available in a 4-pin SOT-143 package. Datasheets and support documentation are available on Micrel’s web site at: www.micrel.com.
