TD310IDT from STMicroelectronics, in a SO-16. 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 | VCC | power_in | Supply voltage operates from 4 V to 16 V (absolute maximum 18 V) and should be decoupled with a 1 µF minimum capacitor. |
| 2 | INA | input | CMOS/LSTTL compatible inverting logic input with hysteresis that controls output channel A. |
| 3 | INB | input | CMOS/LSTTL compatible inverting logic input with hysteresis that controls output channel B. |
| 4 | INC | input | CMOS/LSTTL compatible inverting logic input with hysteresis that controls output channel C. |
| 5 | Enable | input | Enable input that, together with the sense comparator and the buffer inputs, determines the buffer outputs. |
| 6 | Alarm | output | Alarm output signals an overcurrent event to the controller, falling within 500 ns of a sense trigger and sinking 5 to 35 mA at VO = 0.8 V. |
| 7 | OA Output | output | Output of the uncommitted operational amplifier, which can be used for current measurement before an A/D input or for other general-purpose use. |
| 8 | OA Input + | input | Non-inverting input of the uncommitted operational amplifier, with a common-mode input range of 0 to VCC - 1.5 V. |
| 9 | Sense + | input | Non-inverting input of the current sense comparator; when it exceeds Sense -, the output drivers are inhibited and the alarm is asserted, with 40 mV sense hysteresis. |
| 10 | OA Input - | input | Inverting input of the uncommitted operational amplifier, with a common-mode input range of 0 to VCC - 1.5 V. |
| 11 | Sense - | input | Inverting (reference) input of the current sense comparator used with Sense + to detect overcurrent. |
| 12 | GND | power_in | Ground reference for the device. |
| 13 | OUTC | output | Driver output channel C, rated for 0.6 A peak with a sourcing drop of 3 V and a sinking drop of 5 V at 200 mA. |
| 14 | OUTB | output | Driver output channel B, rated for 0.6 A peak with a sourcing drop of 3 V and a sinking drop of 5 V at 200 mA. |
| 15 | OUTA | output | Driver output channel A, rated for 0.6 A peak with a sourcing drop of 3 V and a sinking drop of 5 V at 200 mA. |
| 16 | UVLO/Stby | input | Resistor bridge sets the undervoltage lockout (VUVLO = 1.2 V × (R1+R2)/R1, default internal 12 V) and standby mode: low selects standby (30 µA, outputs low), mid selects UVLO, high selects normal operation (1.5 mA). |
