Description
General part information
L9800 Series
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.
