UCC27714 是一款 600V 高侧/低侧栅极驱动器,具有 4A 拉/灌电流能力,专用于驱动功率金属氧化物半导体场效应晶体管 (MOSFET) 或绝缘栅双极晶体管 (IGBT)。 该器件包含一个接地基准通道 (LO) 和一个悬空通道 (HO),后者专用于自举电源操作。 该器件具有出色的稳定性和抗扰度,能够在 HS 引脚上的负电压高达 –8VDC 的条件下(VDD = 12V 时)维持逻辑正常运行。
该器件可接受的偏置电源输入范围宽达 10V 至 20V,并且为 VCC 和 HB 偏置电源引脚提供了 UVLO 保护。 UCC27714 采用 SOIC-14 封装,额定工作温度范围为 –40°C 至 125°C。

NAME | NO. | ||
COM | 5 | – | Return for low-side driver output. |
EN/NC | 4 | I | Enable input for high-side and low-side driver. This pin biased LOW, disables both HO and LO regardless of HI and LI state, This pin biased high or floating enables both HO and LO. |
HB | 13 | I | High-side floating supply. Bypass this pin to HS with a suitable capacitor to sustain boot-strap circuit operation in the desired application, typically 10× bigger than gate capacitance. |
HI | 1 | I | Logic input for high-side driver. If HI is unbiased or floating, HO is held low. |
HO | 12 | O | High-side driver output. |
HS | 11 | – | Return for high-side floating supply. |
LI | 2 | I | Logic input for low-side driver. If LI is unbiased or floating, LO is held low. |
LO | 6 | O | Low-side driver output. |
NC | 8, 9, 10, 14 | – | No connection. |
VDD | 7 | I | Bias supply input. Power supply for the input logic side of the device and also low-side driver output. Bypass this pin to VSS with typical 1-µF SMD capacitor (typically CVDD needs to be 10 × CBOOT). If shunt resistor used between COM and VSS, then also bypass this pin to COM with 1-µF SMD capacitor. |
VSS | 3 | – | Logic ground. |
