L4969集成电路（IC）的专用规格书PDF中文资料

L4969属于集成电路（IC）的专用。由意法半导体集团制造生产的L4969专用该系列产品可提供所需的功能，用以将信息源/信宿连到各种复杂或范围狭窄应用中的传感器、变送器、致动器、传输介质或其他此类端点。例如，汽车安全气囊驱动器、车身控制和信息娱乐总线、自适应电缆均衡器、智能卡等等。

DESCRIPTION

The L4969 is an integrated circuit containing 3 independent Voltage Regulators and a standard fault tolerant low speed CAN line interface in multipower BCD3S process.

It integrates all main local functions for automotive body electronic applications connected to a CAN bus.

■ OPERATING SUPPLY VOLTAGE 6V TO 28V, TRANSIENT UP TO 40V

■ LOW QUIESCENT CURRENT CONSUMPTION, LESS THAN 40µA IN SLEEP MODE

■ TWO VERY LOW DROP VOLTAGE REGULATORS 5V / 200mA AND 5V/200mA

■ SEPARATE VOLTAGE REGULATOR FOR CAN-TRANSCEIVER SUPPLY WITH LOW POWER SLEEP MODE

■ EFFICIENT UC SUPERVISION AND RESET LOGIC

■ 24 BIT SERIAL INTERFACE

■ AN UNPOWERED OR INSUFFICIENTLY SUPPLIED NODE DOES NOT DISTURB THE BUS LINES

■ VS VOLTAGE SENSE COMPARATOR

■ SUPPORTS TRANSMISSION WITH GROUNDSHIFT: SINGLE WIRE: 1.5V, DIFFERENTIAL: 3V
