HXY MOSFET · AC-DC Controllers and Regulators · SOP-16
SG3525-HXY from HXY MOSFET, in a SOP-16. 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 | Inv. Input | input | Inverting input of the internal error amplifier. Common-mode range includes the 5.1 V reference so no external divider is required when regulating to VREF. |
| 2 | Noninv. Input | input | Non-inverting input of the internal error amplifier. Typical input offset 1.5 mV, bias current 1 µA, CMRR 90 dB. |
| 3 | Sync | bidirectional | Oscillator sync input/output for master/slave operation or synchronization with an external clock. Sync threshold typ 2 V; sync input current typ 1.3 mA at 3.5 V. |
| 4 | OSC. Output | output | Oscillator clock output. Provides the internal clock signal (typ 3 V amplitude, 0.6 µs width) for external use or scope monitoring. |
| 5 | CT | passive | Oscillator timing capacitor. Combined with RT (pin 6) sets the switching frequency (100 Hz-500 kHz range). Typical charging current 50 µA. |
| 6 | RT | passive | Oscillator timing resistor. Sets the oscillator charge current; typical range 2 kΩ (430 kHz) to 200 kΩ (60 Hz-120 Hz) with the corresponding CT. |
| 7 | Discharge | passive | Deadtime/discharge pin. A resistor between CT (pin 5) and Discharge sets the oscillator discharge time, which controls the deadtime between the A and B outputs. |
| 8 | Soft-Start | passive | Soft-start capacitor pin. An internal 50 µA current source charges the external capacitor to ramp up the duty cycle at startup. Typical soft-start current 51 µA. |
| 9 | Compensation | output | Error amplifier output and PWM comparator input. Loop compensation network (typically a resistor and capacitor to Inv. Input) is connected here. |
| 10 | Shutdown | input | Active-high shutdown input. Threshold typ 0.8 V (min 0.6 V, max 1 V). Asserting shutdown initiates the pulse-by-pulse latch-off, discharges the soft-start capacitor, and disables both outputs. |
| 11 | Output A | output | Push-pull totem-pole gate driver output A. Sources/sinks >200 mA (500 mA absolute max). Alternates with Output B; typ rise/fall 80 ns / 70 ns into 1 nF. |
| 12 | Ground | power_in | Signal and power ground return for the device. |
| 13 | VC | power_in | Collector supply for the output driver stage. Rated 40 V absolute maximum; usually tied to VCC but can be biased separately to drive gates from a different rail. |
| 14 | Output B | output | Push-pull totem-pole gate driver output B. Complementary phase to Output A for push-pull / half-bridge / full-bridge topologies. Same drive spec as Output A. |
| 15 | VCC | power_in | Main supply input. Operating range 8-35 V; 40 V absolute maximum. UVLO turns the device on around 7 V typical (6-8 V) with hysteresis. Typical ICC 12 mA. |
| 16 | Vref | power_out | 5.1 V ±1% precision reference output. Short-circuit current typ 80 mA (limit 100 mA); intended for biasing external circuitry, decouple with ~0.1 µF to ground. |
