SPIDER
Multichannel SPI Driver Enhanced Relay Control
SPIDER products are highly integrated multichannel SPI drivers for small current loads such as relays and solenoids, LEDs, small bulbs, and stepper motors. SPIDER devices are designed to be used in automotive and industrial applications with dedicated feature sets. The SPIDER family consists of an 8-channel low-side device with four PWM inputs, high current capability (up to 1 A), and daisy-chain capability.
- 16-bit SPI interface
- Four PWM inputs
- Current capability up to 1 A
- Overload protection
- Overvoltage protection
- Overtemperature protection
- Short-circuit protection
- AEC qualified
Automotive applications of SPIDER
The most common automotive application for SPIDER is in the body control module (BCM) arena, where a high number of relays, indicators, and actuators distributed throughout the vehicle are controlled and diagnosed. However, SPIDER serves almost any automotive electronic control unit (ECU), for example, power distribution box, HVAC flap control, smart mirror control, e-shift, steering wheel vibration (lane change alert), and many others.
Industrial applications of SPIDER
The most common industrial application for SPIDER is driving relays, indicators, and actuators in white goods electronic control units. The SPI communication interface allows the user to reduce the pin count of the microcontroller. This results in system cost savings and more precise diagnosis and protection.
Features of SPIDER
The device is protected by embedded protection functions and designed for automotive and industrial applications. The output stages are controlled via an SPI interface. Additionally, four channels can be controlled in parallel for PWM applications. These features make the TLE7230R particularly suitable for engine management and body systems.
