L9848
OCTAL CONFIGURABLE LOW/HIGH SIDE DRIVER
s Configurable up to 6 high side drivers
s R_DSON=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
SO28
ORDERING NUMBER: L9848
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
