Material Declaration:
The L9800 is an 8-channel LS driver designed for automotive applications (LEDs and relays) and compatible with resistive, inductive and capacitive loads. The device offers advanced diagnostic and protection functionalities such as open load, overcurrent and overtemperature detections, short to GND. The eight output channels can be driven by SPI or by dedicated parallel inputs. Limp-home functionality is present. Daisy chain available (no constraint on SPI number of bits of devices in chain). The device is able to guarantee cranking scenario down to VBATT = 3 V and ensures very low-quiescent current under RESET.
The device is an 8-channel low-side power switch in a TFQFN24 4x4x0.9 package. It is specially designed to control relays and LEDs in automotive and industrial applications.
A serial peripheral interface (SPI) is used for control and diagnosis of the loads as well as of the device. For direct control and PWM there are two input pins (IN0 and IN1) available, connected to two outputs by default (OUT2 and OUT3). Additional or different outputs can be controlled by the same input pins if programmed by SPI.
- AEC-Q100 qualified
- Full ISO26262 compliant, ASIL-B systems ready
- General
- Eight LS drivers
- 16-bit SPI interface for outputs control and for diagnosis data communication
- Daisy chain compatible and available even with 8-bit SPI
- 2 parallel input pins with input mapping functionality
- Cranking capability down to VBATT = 3 V
- Digital supply voltage range compatible with 3.3 V and 5 V MCU
- Bulb inrush mode (BIM) to drive 2 W lamps and electronic loads
- Two independent internal PWM generators for MCU offloads and to drive LEDs
- Very low quiescent current (with usage of IDLE pin)
- Limp-home mode (with usage of IDLE and IN pins)
- Safety features Temperature sensor and monitoring Serial communications using address feedback, 1 parity bit, frame counter and short frame detection
- Fail-safe activation via input pins
- Safe operation at low battery voltage (cranking)
- Protective functions
- Overcurrent latch off
- Lower supply voltage range for extended operation
- Electrostatic discharge (ESD) protection
- Reverse battery protection on VBATT without external components
- Short circuit battery protection
- Thermal shutdown latch off
- Diagnostic features
- Latched diagnostic information via SPI register
- Overcurrent and overtemperature detection at on state
- Off state diagnosis, able to detect and distinguish open load and short to GND conditions
