FUNCTIONAL DESCRIPTION
General Features
The L9848 IC is a monolithic integrated circuit, which provides high flexibility for driving medium loads. 8 out-
puts, whereof 6 (Output1-6) can be used as either internal low or high side drives in any combination and 2 are
dedicated low side outputs (Output7-8). The use of this device reduces the I/O port requirements of the micro-
processor by having serially controlled outputs via a SPI interface. In addition, Output5-6 are capable of being
PWMed via an external pin (Input5-6). The 8bit SPI input is used to command the 8 output drivers either ON or
OFF and additional to indicate latched fault conditions that may have occurred. Multiple L9848s may be daisy-
chained with one additional microprocessor I/O port (CSn) for each device. The implemented self-configuration
allows the user to connect a high or low side load to any of these outputs and the L9848 will drive them correctly
