Description
The L9301 is a SPI (Serial Peripheral Interface)
controlled octal channel with 4 high/low and 4 low
side drivers with the possibility to use four
integrated PowerMOS as recirculation diodes for
PWM load driving.
L9301 contains 12 PowerMOS: 4 configurable
High/Low side drivers with Ronmax = 0.6 Ω
(DRN1-4, SRC1-4), 4 low side drivers with
Ronmax = 0.6 Ω (OUT1-4) and 4 low side drivers
with Ronmax = 0.3 Ω (OUT5-8).
The power DRN/SRC1-4 and OUT1-4 can be
connected in parallel outside the device in order
to get 4 low-side drivers with Ronmax = 0.3 Ω:
DRN1//DRN2, DRN3//DRN4, OUT1//OUT2,
OUT3//OUT4.
In this way there is a total of 8 LS channels for
ON-OFF mode with Ronmax = 0.3 Ω.
There is also the possibility to connect the OUT1-
4 and OUT5-8 in order to drive in PWM mode a
load connected to VB or GND without the
necessity of a freewheeling diode. In this case the
Ronmax = 0.6 Ω.
The above configuration can be driven by parallel
input or SPI command.
Through the SPI it is possible to configure the
device parameters like configuration, Slew-rate,
Overcurrent threshold, to send the drivers
commands and to read back the diagnosis
results.
