TPS389001DSER Overview

Features
  • 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) return above the respective thresholds. The TPS3890 family uses a precision reference to achieve 1% threshold accuracy. The reset delay time can be user-adjusted between 40 μs and 30 s by connecting the CT pin to an external capacitor. The TPS3890 has a very low quiescent current of 2.1 μA and is available in a small 1.5-mm × 1.5-mm package, making the device well-suited for battery-powered and space-constrained applications. The device is fully specified over a temperature range of –40°C to +125°C (TJ).
