1 / 18 page ![]() 1/18 L9848 July 2003 s Configurable up to 6 high side drivers s RDSON=max.1.5Ω@Tj=25°C s Current limit of each output at min. 0.8A s Supply voltage 4.75V to 5.25V s Output voltage clamping min. 35V (low side mode) s Output voltage clamping -30V (high side mode) s SPI interface for data communication s Additional PWM inputs for 2 outputs s Thermal shutdown for all outputs s Open load detection in off mode s Reverse battery protection for outputs (amb) s 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 periph- eral interface (SPI) controls all outputs and provides diagnostic information. Integrated clamping circuits, waveshaping, protec- tion against positive and negative voltage transients and thermal shutdown for all outputs open a wide range of automotive and industrial applications SO28 ORDERING NUMBER: L9848 OCTAL CONFIGURABLE LOW/HIGH SIDE DRIVER BLOCK DIAGRAM Prepared by G.
