Single Axis Motor Module

Описание:
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 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

Описание:
This reference design drives a two-speed front windshield wiper, one or two rear wipers, and the pump, which sprays the front and back windshields in an automobile. In addition to controlling the brushed motors for the wipers and pump, this design includes inputs for wiper parking signals as well as diagnostic and protection features. Test data demonstrates the performance of the design with typical automotive wiper mechanisms, and complete design files can accelerate new project development for automotive designers.
Возможности:

Drives front and rear wiper motors Drives bi-directional spray wash pump Operates from 12-V automotive battery, with reverse battery and load-dump protection On-board 3.3-V power supply and simple controller interface This circuit design is tested and includes schematics, test data, and layout description.
