Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; 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 range is -0.3 V to VCC-2 V. |+| 2 | 1IN- | input | Inverting input of error amplifier 1. Common-mode input range is -0.3 V to VCC-2 V. |+| 3 | FEEDBACK | bidirectional | Feedback / PWM comparator input. The wired-OR outputs of both error amplifiers appear here and are compared with the oscillator ramp. Input threshold ~4.5 V (zero duty cycle); can source ~2 mA and sink ~0.3 mA. |+| 4 | DTC | input | Dead-time control input. A voltage on this pin sets the minimum dead-time (maximum duty cycle). 0 V gives maximum duty cycle; ~3.3 V forces zero duty cycle. Input bias current ~10 uA over 0-5.25 V. |+| 5 | CT | passive | Oscillator timing capacitor connection. External capacitor to GND sets the oscillator frequency together with RT (typ. C=0.01 uF, R=12 k gives ~10 kHz). |+| 6 | RT | passive | Oscillator timing resistor connection. External resistor to GND sets the oscillator charging current and, together with CT, the oscillator frequency. |+| 7 | GND | power_in | Device ground return. |+| 8 | C1 | output | Collector of output transistor 1 (uncommitted). Rated to 500 mA source/sink (200 mA recommended), VCE(max) 40 V, VCE(sat) ~1.3 V @ 200 mA. Used for push-pull (with C2/pin 11) or single-ended output. |+| 9 | E1 | output | Emitter of output transistor 1 (uncommitted). Tie to GND for common-emitter (open-collector) operation or use as an emitter-follower output. |+| 10 | E2 | output | Emitter of output transistor 2 (uncommitted). Tie to GND for common-emitter (open-collector) operation or use as an emitter-follower output. |+| 11 | C2 | output | Collector of output transistor 2 (uncommitted). Rated to 500 mA source/sink (200 mA recommended), VCE(max) 40 V. Used for push-pull (with C1/pin 8) or single-ended output. |+| 12 | VCC | power_in | Main supply voltage. Recommended 7-40 V, absolute maximum 41 V. Standby current ~10 mA at 15 V, ~15 mA at 40 V. |+| 13 | OUTPUT CTRL | input | Output-mode control. Tie to GND for parallel single-ended operation of both output transistors (in phase); tie to VREF (pin 14) for push-pull operation via the pulse-steering flip-flop. Input current ~3.5 mA. |+| 14 | VREF | power_out | 5.0 V internal reference output (4.75-5.25 V @ IO=1 mA, VCC=15 V). Short-circuit current limited to ~50 mA; drift <1 % over -40 to +85 degC. |+| 15 | 2IN- | input | Inverting input of error amplifier 2. Common-mode input range is -0.3 V to VCC-2 V. |+| 16 | 2IN+ | input | Non-inverting input of error amplifier 2. Common-mode input range is -0.3 V to VCC-2 V. Typically tied to GND (or VREF) when only one error amp is used. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HANSCHIP semiconductor |+| Package | SOP-16 |+| Category | PMIC |+| Pins | 16 |++## Ordering variants++- `TL494IDRGTL494CDRG`+- `TL494IDRGTL494CDRG4`+- `TL494IDRG`+- `TL494IDRG4`+- `TL494IDRGTL494CPG`+- `TL494IDRGTL494IPG`+- `TL494IDRGTL494CPWRG`+- `TL494IDRGTL494IPWRG`++## CAD (KiCad official)++- Symbol: `TL494IDRG`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HANSCHIP semiconductor datasheet](docs/tl494idrg-datasheet.pdf) (9 pp, sha256 `bd4b68a7f8cb0624`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
