TPS3899DL26DSER

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

TPS3899DL26DSER 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: a ground-referenced capacitor on this pin sets the RESET/RESET delay before deassertion, with CCTR specified from 0 to 10 µF.
2 CTS passive Capacitor-programmable sense delay: a ground-referenced capacitor on this pin sets the RESET/RESET delay before assertion, with CCTS specified from 0 to 10 µF.
3 GND power_in Ground reference for the device.
4 VDD power_in Supply voltage pin rated 0.85 V to 6 V for DL and PL outputs (absolute maximum VDD + 0.3 V or 6.5 V, whichever is smaller), with a 0.1 µF ceramic capacitor placed close to the pin recommended.
5 SENSE input Monitored voltage input (direct for fixed variants, resistor-divider node for the adjustable variant) rated 0 to 6 V, where RESET asserts below VIT- after the CTS delay and releases above VIT- + VHYS after the CTR delay.
6 RESET output Active-low RESET output for the DL variant (open-drain) that asserts to logic low after the CTS delay when SENSE falls below VIT-, rated 0 to 6 V with output current up to ±5 mA.
