FUNCTIONAL DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
OUTPUTS
5.0 V LINEAR REGULATOR (LDO)
This low dropout linear regulator (V1) outputs a regulated 5.0 V at 200 mA. The associated monitoring circuit provides
detection of under-voltage, over-current, and short-circuit conditions, as well as over-temperature and a reset function.
5.0 V REGULATOR BASE PNP DRIVE
The V2 linear regulator control circuitry provides drive for an external series pass transistor (PNP type). The 5.0 V output tracks
the V1 regulator
HIGH SIDE SWITCH
The high switch provides a 2.0 ohm (typ.) RDSON MOSFET driver connected to the VSUP pin. The output is protected against
short-circuit conditions and provides over-temperature shutdown.
CAN PHYSICAL LAYER INTERFACE
This circuitry provides communication between the TXD & RXD pins, from/to the MCU, and the CANL & CANH pins of the
CAN physical interface. The various modes of the CAN interface are controlled through the SPI control registers.
INTEGRATED SUPPLY
VSUP CONTROL & MONITOR
This circuitry protects the IC from transient conditions such as vehicle jump-start (27 V) and load dump (40 V). If the VSUP
voltage falls below 3.0 V (or a 6.0 V warning interrupt), an under-voltage detection is reported.
