10 / 42 page Obsolete Product(s) - Obsolete Product(s) Electrical Characteristics L8229 10/42 3 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. 3.1 Absolute maximum ratings 3.2 Operating ratings Table 3.
