Texas Instruments · Supervisor And Reset ICs · TSOT-23-8
TPS3435CAKAGDDFR from Texas Instruments, in a TSOT-23-8. 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 | SET0 | input | Logic input that, together with SET1 and WD-EN, selects the watchdog timer scaling and enables or disables the watchdog; logic levels must stay within 0 to VDD. |
| 2 | MR | input | Manual reset input: driving it below 0.3 x VDD asserts WDO, WDO deasserts when it rises above 0.7 x VDD, and it has an internal 100 kΩ pull-up to VDD so it can be left floating, with VMR not to exceed VDD. |
| 3 | WDI | input | Watchdog input: a falling edge must occur on this pin before the watchdog timeout expires, otherwise WDO asserts. |
| 4 | GND | power_in | Ground pin. |
| 5 | SET1 | input | Logic input that, together with SET0 and WD-EN, selects the watchdog timer scaling and enables or disables the watchdog; logic levels must stay within 0 to VDD. |
| 6 | WD-EN | input | Logic input: a logic high enables watchdog monitoring and a logic low disables it; logic levels must stay within 0 to VDD. |
| 7 | WDO | output | Watchdog output, asserted when a watchdog error occurs or MR is driven low; with open-drain output connect a pull-up to VDD, WDO open-drain is rated to 6.5 V and the WDO pin current is limited to ±20 mA absolute maximum (±5 mA recommended). |
| 8 | VDD | power_in | Supply voltage pin specified for 1.04 V to 6.0 V operation, with a 0.1-µF bypass capacitor recommended in noisy systems. |
