说明

Onsemi（前身为 Fairchild）的 FAN7392N 是一款单片式高压侧和低压侧栅极驱动 IC，采用 14 引脚 PDIP 封装，能够驱动工作电压高达 +600V 的 MOSFET 和 IGBT。它具有 3A/3A 源/汇输出电流、3.3V 逻辑兼容输入、独立 VDD 逻辑电源（3.3V 至 20V）、VCC 和 VBS 欠压锁定、逐周期边缘触发关断、双通道匹配传播延迟和共模 dv/dt 噪声消除。功耗为 1.6W。工作温度 -40C 至 +125C。注：该产品处于最后发货状态。.

Onsemi（前身为 Fairchild Semiconductor）的 FAN7392N 是一款采用 14 引脚 PDIP 通孔封装的单片式高压侧和低压侧栅极驱动 IC。它可以驱动工作电压高达 +600V 的 MOSFET 和 IGBT，适用于半桥和全桥逆变器应用。注：该产品在 onsemi 处于最后出货状态，这意味着它已接近报废期，不应设计到新产品中。.

FAN7392 提供独立的高压侧和低压侧栅极驱动输出（HO 和 LO），每个输出都能提供 3A 源电流和 3A 灌电流。缓冲输出级采用全 NMOS 晶体管，具有高脉冲电流驱动能力，并在开关转换期间将交叉传导降至最低。.

该高压侧驱动器采用自举浮动电源 (VB-VS)，允许工作电压高达 +600V。 Onsemi 的高压工艺和共模噪声消除技术可在高 dv/dt 噪声环境下稳定工作。先进的电平转换电路可在 VBS = 15V 时提供低至 VS = -9.8V（典型值）的高压侧栅极驱动器工作，这对于会出现负 VS 瞬变的电机驱动应用至关重要。.

逻辑输入（HIN、LIN、SD）与标准 CMOS 或 LSTTL 输出兼容，逻辑电压低至 3.3V。独立的 VDD 逻辑电源引脚（3.3V 至 20V）允许与 3.3V 微控制器直接连接，无需电平转换。SD（关断）引脚为两个通道提供逐周期边缘触发关断功能，适用于过流保护。.

当 VCC（低压侧电源）和 VBS（高压侧电源）低于规定的阈值电压时，欠压锁定（UVLO）电路可防止误动作，确保 MOSFET/IGBT 不会在上电期间进入线性工作状态。.

两个通道的传播延迟相匹配（典型值为 130 ns 接通，150 ns 关断），可在桥式配置中实现精确的互补开关。输出与输入信号同相（HIN=高，HO=高）。.

PDIP-14 封装在 25C 环境温度下的功率耗散为 1.6W，热阻为 75C/W。对于表面贴装应用，还提供 FAN7392MX（SOIC-16W）变体，但也处于最后出货状态。.

对于新设计，onsemi 建议使用 FAN7390 或 NCP51530 作为替代器件。.

**自举高压侧驱动器：** 高压侧驱动器由连接在 VB 和 VS 之间的自举电容器供电。 当低压侧 MOSFET 打开时，VS 接近接地，自举电容器通过自举二极管从 VCC 充电。当高压侧 MOSFET 接通时，VS 上升到总线电压，自举电容为高压侧驱动器提供浮动电源。这样就不再需要隔离电源。.

**电平转换：** 高压侧驱动器以 VS（开关节点）为基准，在高 dv/dt 时在接地和总线电压之间摆动。电平转换电路将接地参考逻辑信号转换为浮动高压侧域。共模 dv/dt 噪声消除电路可防止在这些快速转换期间发生误触发。.

**逐周期关机：** SD（关机）引脚具有边沿触发关机功能。在 SD 上检测到上升沿时，HO 和 LO 都会在开关周期的剩余时间内被强制置低。在下一个 HIN/LIN 转换时，输出恢复正常工作。这提供了快速过流保护，而无需锁定驱动器。.

**UVLO 保护：** VCC 和 VBS 均由欠压锁定电路监控。如果 VCC 低于 UVLO 门限（典型值约为 9.2V），低压侧输出将被禁用。如果 VBS 低于其 UVLO 门限（典型值约为 8.6V），高压侧输出将被禁用。这可防止 MOSFET 在栅极电压不足的情况下被驱动，从而导致过大的传导损耗和潜在的器件故障。.
