TL594CPWR from Texas Instruments, in a TSSOP-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 | 1IN+ | input | Non-inverting input of Error Amplifier 1, common-mode input voltage range -0.3V to VCC-2V |
| 2 | 1IN- | input | Inverting input of Error Amplifier 1 |
| 3 | FEEDBACK | input | Feedback input pin for PWM control; input voltage 0.5V to 3.5V produces duty cycle from 97% to 0% |
| 4 | DTC | input | Dead Time Control Comparator input for controlling minimum dead time from 3% to 100%; input range 0V to 3.3V |
| 5 | CT | passive | Capacitor terminal for setting oscillator frequency with external CT capacitor; frequency range 1kHz to 300kHz with appropriate CT and RT values |
| 6 | RT | passive | Resistor terminal for setting oscillator frequency; external RT timing resistor value range 1.8kΩ to 500kΩ |
| 7 | GND | power_in | Ground reference for all internal circuits |
| 8 | C1 | output | MOSFET Output 1 drain terminal, 200mA maximum source/sink current, saturated voltage <1.3V in common-source configuration |
| 9 | E1 | output | MOSFET Output 1 source terminal, 200mA maximum source/sink current |
| 10 | E2 | output | MOSFET Output 2 source terminal, 200mA maximum source/sink current |
| 11 | C2 | output | MOSFET Output 2 drain terminal, 200mA maximum source/sink current, saturated voltage <1.3V in common-source configuration |
| 12 | VCC | power_in | Positive power supply input; recommended operating voltage range 7V to 40V; absolute maximum 41V |
| 13 | OUTPUT CTRL | input | Output control input for mode selection: ground for single-ended/parallel operation, Vref for push-pull operation |
| 14 | REF | output | 5V reference regulator output with ±1% initial accuracy; can supply 10mA maximum for external bias circuits |
| 15 | 2IN- | input | Inverting input of Error Amplifier 2 |
| 16 | 2IN+ | input | Non-inverting input of Error Amplifier 2, common-mode input voltage range -0.3V to VCC-2V |
