Functional safety information:
Application brief:
The TPS3808E-Q1 family of microprocessor supervisory circuits monitors system voltages from 0.4 V to 5 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. The RESET output remains low for the user-adjustable delay time after the SENSE voltage and manual reset (MR) return above the respective thresholds.
The TPS3808E-Q1 device uses a precision reference to achieve 0.5% threshold accuracy. The reset delay time can be set to 20 ms by disconnecting the CT pin, 300 ms by connecting the CT pin to VDD using a resistor, or can be user-adjusted between 1.25 ms and 10 s by connecting the CT pin to an external capacitor. The TPS3808E device has a very low typical quiescent current of 0.6 µA, and is designed for battery-powered applications. The TPS3808E-Q1 is available in the SOT-23-6 , and is fully specified over a temperature range of –40°C to 125°C (TJ).
- AEC-Q100 qualified with the following results:
- Device temperature grade 1: –40°C to +125°C
- Undervoltage monitoring for power rails
- Reliable monitoring with high threshold accuracy (1% typical)
- Fixed voltage threshold options from 0.9 V to 5 V
- Adjustable voltage option available (0.405 V)
- Separate Sense pin for monitoring and VDD pin for power
- Miniature solution with ultra-low power consumption
- 0.6 µA typical quiescent current
- Compact 6-pin SOT23 package (2.9 mm x 1.6 mm)
- Highly configurable reset time delay to prevent unsafe power on
- Adjustable from 1.25 ms to 10 s
- Separate Manual Reset Input (MR) to assert RESET output on demand
