L99PD08

SPI control diagnosis interface device for

VIPower™ M0-5 and M0-5E high side drivers

Features

8 channel VIPower driver and diagnostics

device

Supports analog and digital VIPower status

readback

8 independent PWM channels

Selectable PWM base clock (2 external, one

internal)

Programmable PWM turn on phase shift

Programmable diagnostic thresholds (analog

VIPower)

Programmable over temperature latch off for

enhanced HSD short circuit reliability

Limp home safety mode

ST-SPI interface protocol for data

communication

External enable pin for low power mode

Detailed and filtered diagnostic for each

channel

Direct multiplexed VIPower status / current

sense feedback

Supply voltage 3.3 or 5.0 V (two pins)

LQFP32

Description

The device has integrated several functions which

save job load of the microcontroller and save

necessary connections to the microcontroller. It’s

possible to connect analog and digital high side

drivers (HSD) to the device and control them via

SPI interface. A synchronous detailed diagnostics

feature is integrated.

The device has 8 outputs to the HSD with the

possibility to be driven either by steady state

ON/OFF mode or by PWM. Two clock inputs used

as base frequency to generate the PWM signal

internally are provided. The outputs are fully

independent and can also be driven with phase

shift to improve characteristics of power net

during the inrush phase. The device has 8 current

sense (CS)/status (ST) pins connected to the

HSD to run diagnostics. The index of ST/CS pin

corresponds to the input connected to the same

HSD channel (ST0/CS0 with OUT0, ST1/CS1

with OUT1 …).

Applications

Exterior and interior automotive light system
