TPS3808 circuit equivalent, programmable-delay supervisory circuit.
* 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
* DSP or microcontroller applications
* Notebook and desktop computers
* PDAs and hand-held products
* P.
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..
