Reverse polarity is standard protection required in an automotive environment. When battery cables are detached and reconnected there is a probability of connecting the wires to wrong terminals of the battery. This mistake could damage the components in Electronic Control Units (ECU). To avoid damage to the ECU there is a need for reverse polarity protection. Schotky diodes could be used but will have a constantly high power loss. This reference design uses the LM5050-Q1 along with n-channel mosfet to provide reverse polarity protection and reduce the power dissipation.
Возможности:

Reverse polarity protection for 12V/24V/48V Oring controller to connect multiple batteries Improves system efficiency and very low quiescent current Replaces the Schottky diode and reduces the power dissipation ISO7637-2 and ISO16750-2 compliant

The TIDA-01389 is a small-footprint motor control module intended for sunroof and window lift applications. This TI Design uses the DRV8703-Q1 gate driver with an integrated current-shunt amplifier alongside two dual-package automotive-qualified MOSFETs, to create a very small power stage layout compared to typical relay solutions. This design also includes two of TI’s DRV5013-Q1 latching hall sensors, which are used to encode the motor position.
Возможности:

15-A motor drive Low component count Anti-pinch detection Reverse battery protection 2-bit hall encoder Motion profiling using pulse width modulation (PWM) input

The demand to retain memory on the position of the seat, window, sliding door, mirror, lift-gate, and others driven by that motor has increased as small motors within the modern automotive vehicle continue to evolve. Existing solutions utilize multiple magnetic sensors attached to the body of a motor to provide a feedback loop to the motor control module. A sensorless approach provides redundancy for existing solutions and, in some cases, removes the requirement for motors with sensors attached. The sensorless approach has become increasingly popular through the implementation of an in-line, current-sense signal-conditioning circuit. This reference design provides a solution that is easily modifiable for many automotive motor systems that control position measurement.
Возможности:

Configurable for many DC motor solutions -14V to 80V wide common mode input range for in-line motor current sensing Operational for typical 9V to 18V battery supply Simple interfacing with MSP430™ LaunchPad™ Development Kit for digital capture

The TIDA-01428 reference design implements a 1-A, wide-VIN, buck converter to 3.3 V followed by a compact, low-input voltage, fixed 5-V boost converter for powering a controller area network (CAN) physical layer interface. The design has been tested for CISPR 25 radiated emissions and conducted emissions using the voltage method and for immunity to bulk current injection (BCI) per ISO 11452-4 with CAN communication operating at 500 KBPS. The TIDA-01428 is an EMC-vetted power tree plus CAN reference design that can be used in many automotive applications. A system basis chip (SBC) is an integrated circuit (IC) that combines many typical building blocks of a system, which includes transceivers, linear regulators, and switching regulators. While these integrated devices can offer size and cost savings in a number of applications, the integrated devices do not work in every case. For applications where an SBC is not a good fit, it might be beneficial to build a discrete implementation of these aforementioned building blocks thus making a discrete SBC.

The TIDA-01429 reference design implements a wideinput voltage boost controller, followed by a wide input voltage buck converter set to 5.0 V. The 5.0 V supply is used for powering a Controller Area Network (CAN) transceiver and a compact fixed 3.3 V linear drop-out (LDO) regulator for supplying the C2000 microcontroller. This design has been tested for CISPR 25 radiated emissions per absorber lined shielded enclosure (ALSE) method, CISPR25 conducted emissions via the voltage method, and for immunity to Bulk Current Injection (BCI) per ISO 11452-4, all with CAN communication operating at 500 KBPS. This is a electromagnetic compliance (EMC) vetted 3-stage power tree with controller area network (CAN) reference design that can be used in many automotive applications requiring operation with input voltages as low as 3.5 V. A system basis chip (SBC) is an integrated circuit (IC) that combines many typical building blocks of a system, which includes transceivers, linear regulators, and switching regulators. While these integrated devices can offer size and cost savings in a number of applications, the integrated devices do not work in every case. For applications where an SBC is not a good fit, it might be beneficial to build a discrete implementation of these aforementioned building blocks thus making a discrete SBC.
