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 | SENSE | input | Input for the monitored supply rail; RESET is driven low when SENSE rises above the overvoltage threshold VIT+ or falls below the undervoltage threshold VIT-. Connect to VDD to monitor the VDD supply. |+| 2 | VDD | power_in | Supply voltage input; a 0.1-µF ceramic capacitor should be placed close to this pin for good analog design practice. |+| 3 | CT | input | Capacitor time-delay pin: connecting it to VDD or leaving it floating selects one of two fixed reset delays, and an external capacitor to ground programs the delay time. |+| 4 | RESET | output | Active-low open-drain output that goes low when SENSE is above VIT+ or below VIT-; it must be connected to a pull-up resistor tied to the desired pull-up voltage. |+| 5 | GND | power_in | Ground reference pin. |+| 6 | MR | input | Manual reset input: pulling it to logic low (VMR_L) asserts reset, and the reset delay (tD) starts after MR is released; MR can be left floating when not in use. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | WSON-6(1.5x1.5) |+| Category | Power Management (PMIC) |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `TPS3703A3250DSER`+- Footprint: `Package_SON:WSON-6_1.5x1.5mm_P0.5mm`+- 3D model: WSON-6(1.5x1.5) (KiCad packages3D, STEP)+- 3D model files: `tps3703a3250dser-etched.step` / `tps3703a3250dser-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps3703a3250dser.step` / `tps3703a3250dser.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tps3703) (40 pp, sha256 `674de0c21ff2714f`, retrieved 2026-10-07, tier: lcsc)+- **Datasheet language:** Chinese.
