Datasheet AS8650A High-efficient Power Management Device with High-speed CAN Interface 1 General Description 2 Key Features The AS8650A is a companion IC which combines power management functions and a fully conforming high-speed CAN Transceiver in one high performance analog device for automotive applications. The AS8650A is powered by the battery, provides 4 output voltage levels of which 3 outputs can be individually programmed in the range of 1.8V to 3.3V with a maximum current consumption up to 120mA at the LDO voltage regulator outputs. An integrated DCDC converter with a very high efficiency for the 5V output supplies the 3 voltage regulators and ensures a voltage stability of ± The combination of DCDC converter with lowdrop-out voltage regulators makes the AS8650A suitable for all Automotive Control Units where power efficiency is a must. The AS8650A provides a high-speed CAN interface up to 1Mbps communication rate conforming to ISO The AS8650A provides wake-up via remote wake-up at CAN bus lines and a local wake pin. The watchdog unit provides three different timing functions start-up, window- and time-out watchdog configurable via the SPI and interface. Voltage monitoring is implemented for the battery supply, DCDC output and the 3 LDO regulator outputs. Undervoltage will be signalled on the INTN pin to the microcontroller. All diagnostics and status flags can be accessed with the SPI interface. The product is available in a 36-pin QFN 6x6x0.9 package. converter for 5V output with very high efficiency programmable voltage regulators in the range of 1.8V to 3.3V CAN interface ISO 11898-5 with remote wake-up voltage monitoring watchdog functions for start-up, operation, and standby thermal shutdown protection EMC performance with outstanding switching technology for the DCDC converter temperature range from -40°C to +105°C in maximum load conditions 36-pin QFN 6x6x0.9 package 3 Applications The AS8650A provides high efficient and flexible power supply together with state-of-the-art high-speed CAN Interface for automotive control units.The device is pin compatible with AS8550 LIN interface in order to change from CAN to LIN easy.
