UCC2806DW 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 | CURLIM | input | Programs the primary current limit threshold; voltage above 350 mV latches device and requires power cycle restart, below 350 mV allows automatic retry after overcurrent condition. |
| 2 | VREF | power_out | Trimmed 5.1 V ±1% reference output with maximum 5 mA available current; must be bypassed to GND with 0.1 μF minimum ceramic capacitor. |
| 3 | CS-- | input | Inverting input of 3× differential current sense amplifier for pulse-by-pulse current limiting. |
| 4 | CS+ | input | Non-inverting input of 3× differential current sense amplifier for pulse-by-pulse current limiting. |
| 5 | NI | input | Non-inverting input of the error amplifier for voltage feedback control. |
| 6 | INV | input | Inverting input of the error amplifier for voltage feedback control. |
| 7 | COMP | output | 2 MHz error amplifier output and PWM comparator input with low output impedance; internally current limited to allow sinking or sourcing current and forcing COMP to GND commands zero duty cycle. |
| 8 | CT | passive | Oscillator timing capacitor connection point charged by current set at RT and discharged to GND through 2.5 mA current sink to initiate next switching cycle. |
| 9 | RT | passive | Oscillator timing resistor connection point with nominally 1.25 V potential; current mirror is limited to maximum 100 μA requiring RT greater than 12.5 kΩ. |
| 10 | SYNC | bidirectional | Bidirectional TTL-compatible pin for external synchronization; outputs oscillator pulses during dead time when free-running, or accepts external clock input when RT forced above 4.4 V; forces outputs low when SYNC high above 2 V. |
| 11 | AOUT | output | High-current gate drive output providing ±200 mA continuous and ±500 mA peak for external MOSFETs; includes inherent anti-parallel body diodes to clamp voltage swings without external clamp diodes. |
| 12 | GND | power_in | Reference ground and power ground for all device functions; bypass and timing capacitors must be connected as close as possible to this pin. |
| 13 | VC | power_in | Power supply input for FET drive outputs with input range 2.5 V to 15 V; must be capacitively bypassed for proper operation. |
| 14 | BOUT | output | High-current gate drive output providing ±200 mA continuous and ±500 mA peak for external MOSFETs; alternates with AOUT and includes inherent anti-parallel body diodes to clamp voltage swings. |
| 15 | VIN | power_in | Power supply input with 8 V to 15 V range internally regulated by 15 V shunt regulator with 25 mA maximum supply current; must be bypassed to GND with 0.01 μF minimum ceramic capacitor. |
| 16 | SHUTDOWN | input | Enhanced protection input that forces AOUT and BOUT low when driven above 1 V threshold (nominal 1.0 V for UCC2806) with 75-150 ns delay to output. |
