Electrical Characteristics

Independently from the selected configurations, L8229 has some electrical characteristics

that are common for all modes. These are listed below while specific characteristics are

listed in their respective functionality descriptions.

In all modes L8229 is powered by Vs supply voltage. The anti cross-conduction delay is

controlled to provide sufficient time for cross-conduction suppression so that at no time both

the upper and lower output devices (on the same side of the H bridge) are allowed to

conduct simultaneously.

During an over-temperature event, when the device Tj is above Tj(shutdown), the internal

thermal protection circuit disables the drive outputs until the device temperature drops below

the lower thermal threshold temperature.

Note:

The programming pins, PROG1 and PROG2, must be soldered to Vcc or to GND and must

not be driven when supplies are on.
