TPS3899PL31DSER 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-adjustable reset delay capacitor pin with capacitor range 0 to 10 µF; capacitor connects to ground to set RESET output deassert delay time. |
| 2 | CTS | passive | User-adjustable sense delay capacitor pin with capacitor range 0 to 10 µF; capacitor connects to ground to set RESET output assert delay time and provides debouncing for monitored voltage noise. |
| 3 | GND | power_in | Ground reference for all device circuits. |
| 4 | VDD | power_in | Analog supply voltage input operating from 0.85 V to 6.0 V for PL variants; 0.1 µF ceramic bypass capacitor placement recommended close to pin. |
| 5 | SENSE | input | Monitored voltage input (0 to 6 V) that when transitioning below negative threshold VIT- asserts RESET after CTS delay, and when transitioning above VIT- + VHYS deasserts RESET after CTR delay; 10 nF to 100 nF ceramic capacitor recommended for noisy applications. |
| 6 | RESET | output | Active-low push-pull output (0 to VDD) that asserts to logic low after CTS delay when SENSE voltage is below VIT- and deasserts to logic high after CTR delay when SENSE voltage exceeds VIT- + VHYS; maximum output current ±5 mA. |
