Function, parameter/code
Overload detection,
Electrical Characteristics Nos. 104/204
SPI Frequency,
Operating Condition Item No. I010
Description and application notes
Overload detection can occur with one or both output channels Q1 and Q2 in
High-Side or in Low-Side configuration if the channels are simultaneously switched.
This sensitivity on signal timing does not exist when configuring both output
channels as Push-Pull.
In general the Overload detection depends on load, signal frequency and slew and
is programmable through SPI. At Overload detection the output channels are set to
high impedance during typical 50 ms and thereafter iC-GF returns to normal mode.
There is no distinction between various effects and reasons causing Overload
detection which has to be handled within the application as for protection at
excessive power dissipation.
At Tj = -40 to -20 °C the maximum SPI frequency is limited to 3 MHz.
