汽車車體控制模塊驅動器(BCM)參考設計TIDA-00296
TIDA-00296 is a reference design that highlights TI’s high-side and low-side relay, motor, and load driver portfolios. The loads for this design (door locks, window lifts, seat heaters, HVAC, lamps, and LEDs) were chosen to show the range of loads that a BCM can drive and how TI’s solutions fit into these areas.
BCM參考設計TIDA-00296主要特性:
Robust and versatile driver products for driving various loads:
High-side pre-FET Drivers (LM9061/TPIC44H01)
Seat Heaters
Low-Side Driver (TPL7407L)
Lamps
High-Side Driver (LMD18400/TPS1H100-Q1)
HVAC Blower, Window/Windshield Actuators
Linear LED Driver (TPS92630)
LEDs
Smart drivers have diagnostic and protection capabilities via I2C and SPI
Reverse polarity protection on the power stage of the design
pre-FET drivers are used to drive discrete FETs allowing the design to have flexibility with load driving requirementsHighlights the ability of the BCM to directly drive loads with higher current requirements (~4500mA)
