L4953G集成電路（IC）的特殊用途穩(wěn)壓器規(guī)格書PDF中文資料

L4953G屬于集成電路（IC）的特殊用途穩(wěn)壓器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的L4953G特殊用途穩(wěn)壓器該系列產(chǎn)品用于電源控制、某種形式的轉(zhuǎn)換，適用于特定的復(fù)雜應(yīng)用。因此，各種產(chǎn)品特性集差異較大，包括空燃比傳感器接口、汽車交流發(fā)電機(jī)電壓調(diào)節(jié)、DDR 端接、液體透鏡控制、摩托車轉(zhuǎn)向信號控制、熱電 (peltier) 冷卻器控制、壓電觸覺控制、閥門控制、小型發(fā)動機(jī)管理等。

DESCRIPTION

The L4953G contains a triple voltage regulator and a power switch.

The IC includes a monitoring circuit to warn if a low voltage or no voltage condition is occuring.

In stand-by output is active as long as possible even when in thermal shutdown or any other fault conditions.

The STCAP pin allows the use of a reserve supply capacitor that will hold enough energy for the 5V Stand-byline to allow the μP to store data.

■ 3 OUTPUTS:

9.2V (500mA);

5V (1A);

5V (100mA) STANDBY

■ OUT1 (9.2V) AND OUT2 (5V) WITH INDEPENDENT ENABLE CONTROL FOR STAND BY MODE

■ 2A HIGH SIDE DRIVER WITH CLAMPED OUTPUT (16V)

■ LOGIC OUTPUT FOR:

– SUPPLY UNDERVOLTAGE (LVW)

– OVERVOLTAGE

– THERMAL PROTECTION

■ RESET FUNCTION

■ IGNITION COMPARATOR

■ REVERSE BATTERY AND LOAD DUMP PROTECTION

■ THERMAL SHUTDOWN
