TPS389001DSET

The TPS389001DSET is a low quiescent current, 1% accurate supervisor with programmable delay in 6 pin WSON package. It is a precision voltage supervisor with low-quiescent current that monitors system voltages, asserting an open-drain RESET (complementary) signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR) pin drops to a logic low. The RESET output remains low for the user-adjustable delay time after the SENSE voltage and manual reset 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 40μs and 30s by connecting the CT pin to an external capacitor. It has a very low quiescent current and is available in a small 1.5mm × 1.5mm package, making the device well-suited for battery-powered and space-constrained applications.

• Nominal supply voltage is adjustable down to 1.15 V
• Negative threshold is 1.15V
• Positive threshold is 1.157V
• Very low quiescent current of 2.1μA (typical)
• Precision hysteresis
• Operating temperature range from -40°C to 125°C
