L9848

Octal configurable low/high side driver

Features

■ Configurable up to 6 high side drivers

■ RDSON = max.1.5 @ Tj = 25 °C

■ Current limit of each output at min. 0.8 A

■ Supply voltage 4.75 V to 5.25 V

■ Output voltage clamping min. 35 V (low side

mode)

■ Output voltage clamping -30 V (high side

mode)

■ SPI interface for data communication

■ Additional PWM inputs for 2 outputs

■ Thermal shutdown for all outputs

■ Open load detection in off mode

■ Reverse battery protection for outputs (amb)

■ Ground disconnection for high side configured

outputs

Description

The L9848 IC is a highly flexible monolithic

medium current output driver that incorporates 2

dedicated low side outputs (outputs 7-8) and 6

outputs that can be used as either internal low or

high side drives in any combination (outputs 1-6).

In addition, 2 outputs are capable of being

PWMed via an external pin (outputs 5-6). The

integrated standard serial peripheral interface

(SPI) controls all outputs and provides diagnostic

information.

Integrated clamping circuits, waveshaping,

protection against positive and negative voltage

transients and thermal shutdown for all outputs

open a wide range of automotive and industrial

applications
