Rear Mirror

Описание:
This automotive door control switch reference design showcases a proof-of-concept solution for an automotive door control switch panel that communicates wirelessly to the door side mirror, window lift and door lock mechanisms. Using TI's automotive qualified BLE + MCU CC2541-Q1 system-on-chip solution, this reference design enables cost, weight, and ultimately fuel savings by replacing expensive and heavy cable harnesses.

Возможности:

Simple proof-of-concept design demonstrating TI Bluetooth® low energy for automotive control applications Enables the replacement of wires and harnesses through a robust and mature Bluetooth ultra-low power SoC solution with full Bluetooth low energy certification Dual-power input includes coin cell battery mode for fully independent portable operation Wide input voltage range 3V to 50V LDO for direct car battery operation with integrated reverse battery protection Functionality in start-stop and cold start environments AEC-Q100 qualified device Automotive-qualified CC2541-Q1 available (Note: There is a slight pinout change from CC2541)

This automotive wireless external mirror control reference design showcases a proof-of-concept solution for an automotive power side view mirror that communicates wirelessly with a control switch. Using TI's automotive-qualified BLE + MCU CC2541-Q1 system-on-chip solution, this reference design enables cost, weight, and fuel savings by replacing expensive and heavy cable harnesses. This SoC also pairs seamlessly with TI's integrated H-bridge motor driver solutions, DRV8801-Q1 and DRV8802-Q1, for fold and mirror position adjustment features. Also, to drive the mirror's heating element, TI's single channel integrated smart FET TPS1H100B-Q1 is used.

Описание:
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
