TPS3899DL22DSER

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

TPS3899DL22DSER 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 User-programmable timing pin; connect external capacitor (0-10µF) to ground to set RESET delay time on deassertion.
2 CTS passive User-programmable timing pin; connect external capacitor (0-10µF) to ground to set RESET delay time on assertion.
3 GND power_in Ground connection.
4 VDD power_in Supply voltage input with recommended operating range 0.85V to 6V; place 0.1µF ceramic bypass capacitor close to pin.
5 SENSE input Voltage monitoring input with operating range 0V to 6V; connect to monitored voltage or resistor divider; optional 10-100nF capacitor may improve performance in noisy applications.
6 RESET tri_state Open-drain active-low output that pulls low after CTS delay when SENSE voltage falls below negative threshold VIT-; releases to high-impedance when SENSE rises above VIT- + VHYS after CTR delay expires.
