UCC2806MTR from Texas Instruments, in a SSOP-16-150mil. 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 | CURLIM | input | Programs the primary current-limit threshold and selects latching versus retry after an overcurrent, with the pin held above 350 mV keeping the device latched. |
| 2 | VREF | power_out | Provides a 5.1 V ±1% trimmed reference output with 5 mA maximum available current, and must be bypassed to GND with at least a 0.1-µF ceramic capacitor. |
| 3 | CS-- | input | Inverting input of the 3× differential current-sense amplifier. |
| 4 | CS+ | input | Non-inverting input of the 3× differential current-sense amplifier. |
| 5 | NI | input | Non-inverting input of the error amplifier. |
| 6 | INV | input | Inverting input of the error amplifier. |
| 7 | COMP | output | Output of the error amplifier and input to the PWM comparator, which is internally current limited so that zero duty cycle is commanded by forcing COMP to GND. |
| 8 | CT | input | Oscillator timing capacitor connection, charged by the RT current and discharged to GND through a 2.5-mA sink to set switching frequency and dead time. |
| 9 | RT | input | Oscillator timing resistor connection, nominally at 1.25 V, where the mirrored current is limited to 100 µA so RT must be greater than 12.5 kΩ. |
| 10 | SYNC | bidirectional | Bidirectional TTL-compatible synchronization pin that outputs a pulse during oscillator dead time in free-run, and becomes an input with the oscillator disabled when RT is forced above 4.4 V. |
| 11 | AOUT | output | High-current gate drive output for the external MOSFET, alternating with BOUT with duty cycle variable from 0% to 50%. |
| 12 | GND | power_in | Reference ground and power ground for all functions of the device, with bypass and timing capacitors to be connected as close as possible to this pin. |
| 13 | VC | power_in | Input supply connection for the FET drive outputs, with an input range of 2.5 V to 15 V, and it should be capacitively bypassed. |
| 14 | BOUT | output | High-current gate drive output for the external MOSFET, alternating with AOUT. |
| 15 | VIN | power_in | Input supply connection for the device, internally limited by a 15 V shunt regulator with shunted supply current limited to 25 mA and bypassed with at least a 0.01-µF ceramic capacitor. |
| 16 | SHUTDOWN | input | Provided for enhanced protection, where driving SHUTDOWN above 1 V forces AOUT and BOUT low. |
