Heated / Cooled Seats

Описание:
An inductive sensing (LDC)-based event counting design providing a robust and low-cost interface for speed measurement and event counting applications. The solution doesn't require magnets and reliably operates in environments with dirt, moisture or oil that usually pose challenges for alternate sensing technologies.
Возможности:

Highly reliable, contactless event counter using LDC technology No calibration required Measurement of >300 events / second No permanent magnets required; operates effectively even with magnetic or electrical enviromental interference

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-01330 reference design implements the drive circuits for two independent brushed DC motors. It provides a solution for automotive power seats with a highly integrated 2-axis driver, reducing the overall bill of materials. The interface to a simple microcontroller Illustrates how the design reduces the processing burden on the control software. In addition to the drive circuit for two motors, this design also includes current feedback sense circuits and other diagnostic features to ensure reliable operation and detection of faults. The control circuit for an LED illumination element is included, as well as the ability to provide tactile feedback to the seat occupant by vibrating in either axis.
Возможности:

Drives two independent brushed DC motors Up to 10 amps motor current (each axis) Current feedback on each axis Reverse battery protection Simple microcontroller interface This circuit design is tested and includes hardware, test results, and a getting started guide

The TIDA-01357 reference design offers a DC motor control solution for multiple automotive HVAC flap actuators or dampers. This design demonstrates a cost-effective motor driver solution for six flap actuators/dampers where all six motors can be driven simultaneously with an output current up to 0.4 A per motor. This reference design maintains a small solution size and low quiescent current in addition to offering reverse battery and load dump protection.
Возможности:

Direct battery operation (12V system); survives voltages up to 45V Withstands reverse battery conditions and load dump conditions (12V system) Three-chip solution to drive up to six motors Compact layout; does not require external FETs Overcurrent, undervoltage and overtemperature protection with diagnostics feature
