Texas Instruments · Power Management - Specialized · SOIC-16-300mil
UC3907DW from Texas Instruments, in a SOIC-16-300mil. 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 | C/S OUT | output | Output of the current-sense amplifier, whose gain is internally fixed at 20; an external capacitor to ground can reduce its bandwidth. |
| 2 | C/S (+) | input | Non-inverting differential input of the current-sense amplifier for an external shunt in the power-return line, with common-mode range up to VCC − 2 V. |
| 3 | C/S (-) | input | Inverting differential input of the current-sense amplifier, used with C/S (+) to set a maximum shunt drop between 50 mV and 500 mV. |
| 4 | (-) SENSE | input | High-impedance remote sense of system ground, treated as the true ground to which all voltages are referenced. |
| 5 | POWER RETURN | power_in | Most negative supply return, which can range from 0 V to 5 V below (-) SENSE and should be connected as close to the power source as possible. |
| 6 | ARTIFICIAL GND | passive | Low-impedance internal ground exactly 250 mV above (-) SENSE that supplies the control bias and operating currents. |
| 7 | VREF | power_out | Bandgap reference set at 2.0 V with respect to (-) SENSE (±1.5%), with undervoltage lockout until the reference is in regulation. |
| 8 | ISET | output | Current-sinking drive amplifier output, normally set by a resistor to ground, with a 0.25 V to 4.1 V signal available in non-isolated use. |
| 9 | OPTO DRIVE | output | Current-sinking output for driving an optocoupler biased from 4.5 V to 35 V, with current up to 20 mA. |
| 10 | VCC | power_in | Supply input for the device, specified for 4.5 V to 35 V operation with a 4.4 V typical undervoltage lockout startup threshold. |
| 11 | (+) SENSE | input | High-impedance sense input of the voltage feedback amplifier, at which the 2 V reference is trimmed to ±1.25%. |
| 12 | COMP | passive | Voltage error amplifier output and compensation node, clamped internally to 2.0 V, where overall loop compensation is normally applied. |
| 13 | ADJ INPUT | input | Input of the transconductance adjust amplifier, which carries a built-in 50 mV offset on its inverting input. |
| 14 | ADJ OUT | output | Adjust amplifier output that can raise the reference seen by the voltage amplifier by up to 100 mV (about 5% range) for current sharing. |
| 15 | CURRENT SHARE BUS | bidirectional | Common share bus connecting all paralleled modules, protected against shorts to ground and voltages up to 50 V. |
| 16 | STATUS INDICATE | output | Open-collector output that is pulled low to flag the module acting as master, with a sink current rating of 20 mA. |
