TPS386000 datasheet


Description :

The TPS386000, TPS3860x0 family of supply voltage supervisors (SVSs) can monitor four power rails that  are greater than 0.4V and one power rail less than 0.4V (including negative voltage) with a 0.25% (typical) threshold accuracy.

SVS-4 monitors the threshold window using two comparators. The extra comparator can be
configured as a fifth SVS to monitor negative voltage with voltage reference output VREF.
The TPS3860x0 has a very low quiescent current of 11μA (typical) and is available in a small, 4mm x 4mm, QFN-20 package.


Features :

1. Adjustable Delay Time: 1.4 ms to 10 s

2. Threshold Accuracy: 0.25% Typical

3. Very Low Quiescent Current: 11 µA Typical

4. Watchdog Timer With Dedicated Output

5. Well-Controlled Output During Power Up

The IC is specially designed for switching power supply system. It provides over-voltage protection, over-current protection, under-voltage protection, on/off control and power good signal generating.
OVP/UVP (Over/Under-Voltage Protection) monitors 3.3V, 5V and double 12V to protect our power supply and PC, FPO goes to high when one of these supply voltages exceeds their normal operation voltage range.

Ordering Informations

ST9S429-PG14 Datasheet

The power supply is turned on after 38mS de-bounce time when PSON signal is set from high to low. To turn off power supply, PSON signal is set from low to high and the de-bounce time is 115mS. When PGI input voltage level is lower than the internal 1.15V reference voltage, after 73uS de-bounce time, the PGO signal is pulled low.
