Furthermore, the family offers to perform precise module diagnosis with best in class current sense accuracy in smart switches in low current regions (kILIS) and ISO 26262-ready documentation supports the use in safety-related applications.Īll in all, the PROFET™ Load Guard is a flexible device to fulfill the needs of upcoming automotive power distribution generations. With the integrated capacitive load switching mode, a broad range of capacitive loads can be charged in the safe operating area.
Exchanging devices within the PROFET™ Load Guard family is simple, as the single and dual-channel devices in the established PG-TSDSO-14 exposed pad package are pin and function compatible. This minimizes design-in efforts by setting up only one design, as the current limit can be adapted on demand if load-driving requirements change. The PROFET™ Load Guard portfolio is characterized by the highest design flexibility, provided by the possibility to adjust the overcurrent limitation of each device, according to the load requirements.
