Steering Column Control Module

Описание:
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

This reference design shows example implementations of how to handle a variety of high-voltage (HV) switch inputs using a multi-switch detection interface (MSDI) device. This user's guide gives real-world examples of a MSDI device handling HV switch inputs for body control module (BCM), faceplate, and top column module (TCM)applications. In addition, the design utilizes a wide-VIN low-dropout (LDO) regulator for creating a fixed 3.3-V microcontroller supply voltage.

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.
Возможности:

Wide-input voltage, fixed 3.3V buck converter Low-input voltage, fixed 5V boost converter Passes Class 4 CISPR 25 radiated emissions Passes Class 4 CISPR 25 conducted emissions Maintains regulated 3.3V and 5V supplies through battery input voltages down to 4.3V Able to survive load dump voltages up to 42V

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.
