描述 Description

NCV7471B/C is a System Basis Chip (SBC) integrating functions typically found in automotive Electronic Control Units (ECUs) in the body domain. NCV7471B/C provides and monitors the low−voltage power supplies for the application microcontroller and other loads, monitors the application software via a watchdog and includes high−speed CAN/CANFD and LIN transceivers allowing the ECU to
host multiple communication nodes or to act as a gateway unit. The on−chip state controller ensures safe power−up sequence and supports low−power modes with a configurable set of features including wakeup from the communication buses or by a local digital signal WU. The status of several NCV7471B/C internal blocks can be read by the microcontroller through the serial peripheral interface or can be
used to generate an interrupt request.

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 wakeup treatment − bus wakeups, local wakeups (via WU pin) and cyclic wakeups (through the on−chip timer)- Generates reset and interrupt requests
• 5 V VOUT Supply from a DC/DC Converter- Can deliver up to 500 mA with accuracy of ±2%- Supplies typically the ECU’s microcontroller
• 11 V (NCV7471B) or 6.5 V (NCV7471C) V_MID Supply from a DC/DC Converter
• Two LIN Transceivers- ISO17987−4, LIN2.X and J2602 compliant- TxD dominant time−out protection
• Protection and Monitoring Functions- Monitoring of the main supply through the V_MID point- Monitoring of VOUT supply output with programmable threshold- VOUT2 supply diagnosis through SPI and interrupt- Thermal warning and thermal shutdown protection- Programmable watchdog monitoring the ECU software
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant
