NCV7428中文资料带 LIN 和 LDO 稳压器的系统基础芯片数据手册ONSEMI规格书

描述 Description

NCV7428 is a System Basis Chip (SBC) integrating functions typically found in automotive Electronic Control Units (ECUs).
NCV7428 provides and monitors the low−voltage power supply for the application microcontroller and other loads and includes a LIN transceiver.

特性 Features

• Control Logic
• - Ensures safe power−up sequence and the correct reaction to different supply conditions- Controls mode transitions including the power management and bus wakeup treatment- Generates reset
• 3.3 V or 5 V VOUT Supply depending on the Version from a Low−drop Voltage Regulator
• - Can deliver up to 70 mA with accuracy of ±2%- Supplies typically the ECU’s microcontroller- Undervoltage detector with a reset output to the supplied microcontroller
• LIN Transceiver
• - LIN2.x and J2602 compliant- TxD dominant timeout protection- Transceiver mode controlled by dedicated input pin
• Protection and Monitoring Functions
• - Thermal shutdown protection- Load dump protection (45 V)- LIN Bus pin protected against transients in an automotive environment- ESD protection level for LIN and VS > ±8 kV
• These are Pb−Free Devices

应用 Application

• Automotive
• Industrial Networks
