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) SO-28 ■ 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 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. 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).
