Texas Instruments · Battery Management · PDIP-16
UC3906N from Texas Instruments, in a PDIP-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 | C/S OUT | output | Current sense amplifier output; absolute maximum output current is 80mA and maximum output current is 40mA typical at VOUT = 2V. |
| 2 | C/S- | input | Current sense comparator inverting input, which is the reference for the 25mV input offset voltage. |
| 3 | C/S+ | input | Current sense comparator non-inverting input, with 0.1µA typical input bias current. |
| 4 | C/L | input | Current limit amplifier input with a 250mV typical threshold below +VIN. |
| 5 | +VIN | power_in | Positive supply input, with an absolute maximum of 40V and a supply under-voltage threshold of 4.5V typical. |
| 6 | GROUND | power_in | Ground; all voltages are referenced to this pin. |
| 7 | POWER INDICATE | output | Open-collector output indicating input power is present, with a 40V maximum output voltage and 20mA maximum output current. |
| 8 | OVER-CHARGE TERMINATE | input | Over-charge terminate input with a 1.0V typical threshold, a 10µA internal pull-up and a -0.3V to +40V input range. |
| 9 | OVER-CHARGE INDICATE | output | Open-collector output indicating the over-charge state, with a 40V maximum output voltage and 20mA maximum output current. |
| 10 | STATE LEVEL CONTROL | output | Open-collector state level control output, with a 40V maximum output voltage and 20mA maximum output current. |
| 11 | TRICKLE BIAS | output | Trickle bias output of the enable comparator for low-current turn-on, with an absolute maximum output current of -40mA. |
| 12 | CHARGE ENABLE | input | Enable comparator input with a threshold of 1.0 times VREF typical, used to enable charging. |
| 13 | VOLTAGE SENSE | input | Voltage amplifier and voltage sense comparator input that regulates at VREF (2.3V typical). |
| 14 | COMPENSATION | passive | Voltage amplifier compensation connection. |
| 15 | DRIVER SOURCE | output | Driver source output that supplies at least 25mA of base drive to an external pass device, with an 80mA absolute maximum driver current. |
| 16 | DRIVER SINK | passive | Driver sink connection, with an 80mA absolute maximum driver current. |
