Description for the TPS386040

The TPS3860x0 family of supply voltage supervisors (SVSs) can monitor four power railsthat are greater than 0.4 V and one power rail less than 0.4 V (including negative voltage) with a0.25% (typical) threshold accuracy. Each of the four supervisory circuits (SVS-n) assert aRESETn or RESETn output signal when the SENSEm input voltage drops below theprogrammed threshold. With external resistors, the threshold of each SVS-n can be programmed (wheren = 1, 2, 3, 4 and m = 1, 2,3, 4L, 4H).

Each SVS-n has a programmable delay before releasing RESETn orRESETn. The delay time can be set independently for each SVS from 1.4 ms to 10 s through the CTnpin connection. Only SVS-1 has an active-low manual reset (MR) input; alogic-low input to MR asserts RESET1 orRESET1.

SVS-4 monitors the threshold window using two comparators. The extra comparator can beconfigured as a fifth SVS to monitor negative voltage with voltage reference output VREF.

The TPS3860x0 has a very low quiescent current of 11 µA (typical) and is available in asmall, 4-mm x 4-mm, VQFN-20 package.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
