Power stages

There are two fixed high-side channels and six channels which can be used either as low-side or as high-side

switches. During the diagnosis in OFF State, the sequences of operations (pull-up or pull-down current source

activation) are determined according to the SPI settings of CFG_0 register.

For the configurable channels, when in high-side configuration, the load is connected between ground and source

of the power transistor (pins SOURCEn, n = 2...7) while the drains (pins DRAINn, n = 2...7) can be connected to

any potential between ground and VBATT.

In low-side configuration, the source of the power transistors must be connected to GND pin potential (either

directly or through a reverse current blocking diode).

The configuration can be chosen for each of these configurable channels individually via SPI.

Operating modes

The ON-state resistance RDS(ON) depends on the supply voltage as well as the junction temperature TJ.

Switching resistive modes

When switching resistive loads, the following switching times and slew rates can be considered.
