Supervisory circuit with a 2.93 V threshold and 130 ms timeout
The TLV803EA29DPWR is a Texas Instruments simple reset/power-on reset supervisor monitoring a single voltage rail. Its 2.93 V threshold catches brownout conditions on a 3.3 V supply before the downstream logic enters an undefined state. Rated for the full industrial temperature span of -40°C to 125°C, this supervisor suits motor-drive control boards or battery-charger circuits where the ambient around the power stage can exceed 85°C.
Package and board-fit for tight layouts
Housed in a 5-X2SON (0.8x0.8 mm) package, the TLV803EA29DPWR occupies a footprint roughly the size of a 0402 resistor. The exposed pad on the 4-XFDFN alternate package aids thermal transfer into the PCB copper pour. Surface-mount assembly with a tape-and-reel or cut-tape option — the reel quantity suits volume pick-and-place while cut tape works for prototype runs or repair stock.
