Description
AI
The TPS386000-Q1 family of voltage supervisors can monitor four power rails that are greater than 0.4 V and one power rail less than 0.4 V (including negative voltage) with a 0.25% (typical) threshold accuracy. Each of the four supervisory circuits (SVS-n) assert aRESETnor RESETn output signal when the SENSEm input voltage drops below the programmed threshold. With external resistors, the threshold of each SVS-n can be programmed (wheren= 1, 2, 3, 4 andm= 1, 2, 3, 4L, 4H).
Each SVS-n has a programmable delay before releasingRESETnor RESETn. The delay time can be set from 1.4 ms to 10 s through the CTn pin connection. Only SVS-1 has an active-low manual reset (MR) input; a logic-low input toMRassertsRESET1or RESET1.
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 TPS386000-Q1 device has a very low quiescent current of 12 µA (typical) and is available in a small, 4-mm × 4-mm, VQFN-20 package.
