In a single 9 x 9 mm QFN package, the ZAMC4100 integrates an ARM Cortex-M0 microcontroller, eight power stages with integrated MOSFETs; SPI, UART and LIN2.1 communication interfaces; eight general-purpose digital input/output (I/O) pins; and four general-purpose analogue inputs.
The company quotes the example application of a compact single-chip solution for the latest generation of automotive premium exterior mirrors. It controls the heater, LEDs and DC motors for mirror adjustment and folding, blind-spot detection, puddle light, defroster and turn signal.
Features of the ZAMC4100 include;
Embedded ARM Cortex-M0 microcontroller
Four integrated low R DSON half-bridge drivers
Four integrated low R DSON high-side switches
Wide input voltage range: 6V-18V (withstands load-dump conditions up to 40V)
Embedded SPI, UART and LIN 2.1 interfaces
Auto-dimming electrochromatic mirror feature
Extensive fault protection and error handling
