SPIDER+ LED
SPIDER+ LED devices combine the feature set of the SPIDER+ family with additional features to drive small bulbs or LEDs
Besides one high-side channel device, three configurable devices support LED designs in the most cost-efficient way with diagnostic and protection features.
- 4 and 8 channels
- 16-bit SPI interface
- Up to 330 mA with all channels ON
- Overload protection
- Open-load detection at OFF
- Overvoltage protection
- Overtemperature protection
- Short-circuit protection
- AEC qualified
- Limp Home mode with IDLE & IN pins
- Bulb Inrush Mode (BIM)
SPIDER+ LED product portfolio
All SPIDER+ LED devices are pin-to-pin compatible with the standard version.
In addition to the standard features already described, the LED pack enables the next functionalities:
- Open-load diagnostics in the ON state – with open-load diagnostics in the ON state, undesirable LED glowing in the OFF state is removed. A diagnostics loop is also available so each channel is diagnosed automatically in synchronization with its control signal, including PWM, reducing the workload of the microcontroller to a simple SPI command.
- Two internal PWM generators – in addition to the two direct input pins, with the two internal PWM generators, up to four different PWM frequency and duty-cycle combinations can be used by the output drivers.
- Bulb Inrush Mode (BIM) – BIM is an auto-retry feature that enables the device to handle inrush currents that would normally latch the output OFF. With BIM, driving small bulbs up to 5 W or other capacitive loads is also possible.
Automotive applications of SPIDER+ LED
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. For SPIDER+ LED devices, the focus is on LEDs and small bulbs as the devices include Bulb Inrush Mode.
Industrial applications of SPIDER+ LED
The most common industrial application for SPIDER+ LED 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. The Bulb Inrush Mode feature can be used to easily supply capacitive loads such as other ECUs, removing the need for fuse protection.
