TPS3807 - Dual-Channel Supervisory Circuit

Description

The TPS3807 family microprocessor supervisory circuits monitor system voltages as low as 1.225V.

These devices assert an open-drain RSTVDD signal when the VDD voltage drops below a preset threshold.

The RSTVDD output remains asserted until the VDD voltage returns above its threshold.

Features

  • Two Supply Monitors in One Package.
  • One Monitor with Fixed High-Accuracy Thresholds for System Supply Monitoring.
  • Second Monitor with Variable Threshold and 30mV Hysteresis to Provide Failsafe.
  • Very Low Quiescent Current: 3.5µA typ.
  • High Threshold Accuracy: 1% max (0°C to +85°C).
  • Open-Drain Reset Outputs.
  • Temperature Range:.
  • 40°C to +85°C.
  • Ultra-Small SC70-5 Package.
