HG7500BN from HGSEMI, in a DIP-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 | AMPERR1+ | input | Non-inverting input of error amplifier 1 (管脚描述: 误差放大器 1+); the datasheet gives no separate voltage limit for this pin. |
| 2 | AMPERR1- | input | Inverting input of error amplifier 1 (管脚描述: 误差放大器 1-); the datasheet gives no separate voltage limit for this pin. |
| 3 | INCPWM | input | PWM comparator input (管脚描述: PWM 比较端); the datasheet gives no separate voltage limit for this pin. |
| 4 | CONTDE | input | Dead-time control input (管脚描述: 死区时间控制); dead-time threshold behaviour is given in the electrical table (terminal 4 threshold voltage 3.3 V typical at 0% duty cycle, 4.2 V typical at maximum duty cycle). |
| 5 | COSC | passive | Oscillator timing capacitor connection (管脚描述: 振荡电容); the oscillator frequency is set with CT and RT, e.g. CT=0.01uF and RT=12k gives 10 kHz typical. |
| 6 | ROSC | passive | Oscillator timing resistor connection (管脚描述: 振荡电阻); the oscillator frequency is set together with COSC, e.g. RT=12k with CT=0.01uF gives 10 kHz typical. |
| 7 | GND | power_in | Ground reference for the controller (管脚描述: 地). |
| 8 | OUT1 | output | Output 1 of the output transistor, which can be configured by CONOUT for push-pull or single-ended operation; output current is rated at Io = 500 mA (absolute maximum 600 mA). |
| 9 | GNDOUT1 | power_in | Output ground for output 1 (管脚描述: 输出地 1). |
| 10 | GNDOUT2 | power_in | Output ground for output 2 (管脚描述: 输出地 2). |
| 11 | OUT2 | output | Output 2 of the output transistor, which can be configured by CONOUT for push-pull or single-ended operation; output current is rated at Io = 500 mA (absolute maximum 600 mA). |
| 12 | VCC | power_in | Power supply pin; absolute maximum supply voltage is 40 V, and quiescent current is 6 mA to 7 mA at VCC = 15 V. |
| 13 | CONOUT | input | Output control pin (管脚描述: 输出控制端) that selects push-pull or single-ended output operation; the datasheet gives control current ICONT of 3.5 mA at VIN = VREF. |
| 14 | VREF | power_out | 5 V reference voltage output (管脚描述: 基准电源), 4.95 V to 5.05 V at VOUT = 1 mA, with short-circuit current of 25 mA to 50 mA at VREF = 0 V. |
| 15 | AMPERR2- | input | Inverting input of error amplifier 2 (管脚描述: 误差放大器 2-); the datasheet gives no separate voltage limit for this pin. |
| 16 | AMPERR2+ | input | Non-inverting input of error amplifier 2 (管脚描述: 误差放大器 2+); the datasheet gives no separate voltage limit for this pin. |
