L4943集成电路（IC）的特殊用途稳压器规格书PDF中文资料

L4943属于集成电路（IC）的特殊用途稳压器。由意法半导体集团制造生产的L4943特殊用途稳压器该系列产品用于电源控制、某种形式的转换，适用于特定的复杂应用。因此，各种产品特性集差异较大，包括空燃比传感器接口、汽车交流发电机电压调节、DDR 端接、液体透镜控制、摩托车转向信号控制、热电 (peltier) 冷却器控制、压电触觉控制、阀门控制、小型发动机管理等。

DESCRIPTION

The L4943 contains a triple voltage regulator and a high side driver. In stand-by the output is active as long as possible even when in thermal shutdown or under any other fault conditions. The STCAP pin allows the use of a reserve supply capacitor that will hold enough energy for the 5V Stand-by line to allow the µP to store data.

■ 3 PROGRAMMABLE OUTPUTS:

♦ 3 TO 11V (500mA);

♦ 3 TO 11V (500mA);

♦ 3 TO 7V (500mA) STANDBY

■ OUT1 AND OUT2 WITH INDEPENDENT ENABLE CONTROL FOR STAND-BY MODE

■ 0.4A HIGH SIDE DRIVER

■ LOAD DUMP PROTECTION

■ THERMAL SHUTDOWN
