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.
