Description
The TPS3808 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.
Features
- Power-on reset generator with adjustable delay time: 1.25 ms to 10 s.
- Very low quiescent current: 2.4 μA typical.
- High threshold accuracy: 0.5% typical.
- Fixed threshold voltages for standard voltage rails
from 0.9 V to 5 V and adjustable voltage down to 0.4 V are available.
- Manual reset ( MR) input.
- Open-drain RESET output.
- Temperature range:.
- 40°C to 125°C.
- Small SOT-23 and 2-mm × 2-mm WSON packages
