ams AS8650B
The AS8650B 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 AS8650B is powered by the battery, provides 4 output voltage levels of which 3 outputs in the range of 1.8V to 3.3V with a maximum current consumption up to 120mA at the LDO voltage regulator outputs. The combination of DCDC converter with low-drop-out voltage regulators makes the AS8650B suitable for all Automotive Control Units where power efficiency is a must.| Part No. | AS8650B |

GENERAL DESCRIPTION
2 KeyFEATURES
An integrated DCDC converter with a very high efficiency for the 5V output supplies the 3 voltage regulators and ensures a voltage stability of ±2.5%. The AS8650B provides a high-speed CAN interface up to 1Mbps communication rate conforming to ISO 11898-5. The AS8650B 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 timeout watchdog; configurable via the SPI and I²C 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.●DCDC converter for 5V output with very high efficiency
●Three voltage regulators providing 3.3V, 2.8V and 1.8V with accuracy better than 2.5% (Two are adjustable through factory settings).
