TPS3899PL42DSER

Texas Instruments · Supervisor And Reset ICs · WSON-6(1.5x1.5)

TPS3899PL42DSER from Texas Instruments, in a WSON-6(1.5x1.5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CTR passive Capacitor programmable reset delay pin; connect to ground-referenced capacitor to set RESET output delay time when deasserting.
2 CTS passive Capacitor programmable sense delay pin; connect to ground-referenced capacitor to set RESET output delay time when asserting.
3 GND power_in Ground connection.
4 VDD power_in Supply voltage pin (0.85V to 6V for PL variants); place 0.1µF ceramic capacitor close to this pin.
5 SENSE input Monitored voltage input; asserts RESET after sense delay set by CTS when below negative threshold VIT-, deasserts after reset delay set by CTR when above VIT- + VHYS; place 10nF to 100nF ceramic capacitor for noisy applications.
6 RESET output Active-low push-pull output; asserts to logic low after CTS delay when SENSE is below negative threshold VIT-, remains low until SENSE rises above VIT- + VHYS and CTR delay expires.
