Product Overview

The TPS389033DSET is a low quiescent current, 1% accurate supervisor with programmable delay in 6 pin WSON package. This precision voltage supervisor monitors system voltages as low as 1.15V, asserting an open-drain active-low RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (active-low MR) pin drops to a logic low. The active-low RESET output remains low for user adjustable delay time after SENSE voltage and manual reset (active-low MR) return above respective thresholds. The TPS3890 uses a precision reference to achieve 1% threshold accuracy. The reset delay time can be user adjusted between 40μs and 30s by connecting CT pin to an external capacitor. The TPS3890 has a very low quiescent current of 2.1μA. It is typically used in battery powered and space constrained applications.
  • Power-on reset voltage of 0.8V
  • High threshold accuracy of 1%
  • Manual reset (active-low MR) input and open-drain active-low RESET output
  • Nominal supply voltage of 3.3V
  • Negative threshold voltage of 3.17V and positive threshold voltage of 3.189 V
  • Power-on-reset (POR) generator with adjustable delay time of 40μs to 30s
  • Supply current (into VDD pin) of 2.09μA at VDD = 3.3V, IRESET = 0mA, -40°C < TJ < 85°C
  • Operating temperature range from -40°C to 125°C
