STPIC44L02集成電路（IC）的驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

STPIC44L02屬于集成電路（IC）的驅(qū)動器接收器收發(fā)器。由意法半導體集團制造生產(chǎn)的STPIC44L02驅(qū)動器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過延長電纜或印制線進行通信。確切的功能會因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對于通信用途可能并非絕對必要，但對于可能的使用環(huán)境卻是明智之選。

DESCRIPTION

The STPIC44L02 is a low-side predriver that provides serial and parallel input interfaces to control four external FET power switches.

It is mainly designed to provide low-frequency switching, inductive load applications such as solenoids and relays. Fault status is available in a serial-data format. Each driver channel has independent off-state open-load detection and on-state shorted load short to battery detection

■ 4-CHANNEL SERIAL-IN PARALLEL-IN LOW SIDE PRE-FET DRIVER

■ DEVICES ARE CASCADABLE

■ INTERNAL 55V INDUCTIVE LOAD CLAMP AND VGS PROTECTION CLAMP FOR EXTERNAL POWER FETS

■ INDEPENDENT SHORTED-LOAD AND SHORT-TO-BATTERY FAULT DETECTION ON ALL GATE TERMINALS

■ INDEPENDENT OFF-STATE OPEN-LOAD FAULT SENSE

■ OVER-BATTERY-VOLTAGE LOCKOUT PROTECTION AND FAULT REPORTING

■ UNDER-BATTERY VOLTAGE LOCKOUT PROTECTION

■ ASYNCRONOUS OPEN-GATE FAULT FLAG

■ DEVICE OUTPUT CAN BE WIRED OR WITH MULTIPLE DEVICES

■ FAULT STATUS RETURNED THROUGH SERIAL OUTPUT TERMINAL

■ INTERNAL GLOBAL POWER-ON RESET OF DEVICE AND EXTERNAL RESET TERMINAL

■ HIGH IMPEDANCE CMOS COMPATIBLE INPUTS WITH HYSTERESIS

■ TRANSITION FROM THE GATE OUTPUT TO A LOW DUTY CYCLE PWM MODE WHEN A SHORTED LOAD FAULT OCCURS
