TPS3890 - 1% Accurate Supervisor

General Description

The TPS3890 is a precision voltage supervisor with low-quiescent current that monitors system voltages as low as 1.15 V, asserting an open-drain RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR) pin drops to a logic low.

Key Features

  • 1 Power-On-Reset (POR) Generator with Adjustable Delay Time: 40 μs to 30 s.
  • Very Low Quiescent Current: 2.1 μA (Typical).
  • High Threshold Accuracy: 1% (max).
  • Precision Hysteresis.
  • Fixed and Adjustable Threshold Voltages:.
  • Fixed Thresholds for Standard Rails: 1.2 V to 3.3 V.
  • Adjustable Down to 1.15 V.
  • Manual Reset (MR) Input.
  • Open-Drain RESET Output.
  • Temperature Range:.
  • 40°C to +125°C.
  • Packag.
