LTC4380的产品详情:

LTC4380 低静态电流浪涌抑制器可保护负载免遭高压瞬变的损坏。它能够通过对一个外部 N 沟道 MOSFET 的栅极电压进行箝位,以在过压过程中 (例如:汽车应用中的抛负载情况) 把输出电压限制在一个安全数值,从而提供过压保护。固定的栅极箝位电压可针对 12V 和 24V / 28V 系统进行选择。对于任何电压高达 72V 的系统,则使用可调栅极箝位版本。该器件还提供了过流保护功能。

一个内部乘法器产生一个与 VDS 和 ID 成比例的 TMR 引脚电流,这样可根据 MOSFET 应力对过流和过压情况下的工作时间加以限制。

GATE 引脚能够驱动背对背 MOSFET 以提供反向输入保护功能,从而免除了采用肖特基二极管解决方案时的电压降和功率耗散。低的 8μA 工作电流允许该器件在始终保持接通和电池供电型应用中使用。一个准确的 ON 引脚比较器负责监视输入电源的欠压 (UV) 情况,而且还充当一个停机输入,从而把静态电流减小至 6μA。

LTC4380的评估套件:

DC2178A-B:LTC4380IDD-2 Demo Board | Low Quiescent Current Surge Stopper, Auto-Retry Version

Demonstration circuit 2178A showcases the LTC4380 low quiescent current surge stopper in an application which can be configured for 12V, 1A or 24V/28V, 0.5A operation. The output voltage is clamped by the LTC4380, permitting the load to operate uninterrupted during transients of up to 250V and load dump surges such as ISO-16750-2 Test A. The output current is limited to 1.25A. In the presence of a sustained input overvoltage or output overcurrent fault the LTC4380 shuts off to prevent damage to the N-channel MOSFET pass element.
