The TPS2HB35-Q1 device is a dual-channel smart high-side switch intended for use in 12-V automotive systems. The device integrates robust protection and diagnostic features to ensure output port protection even during harmful events like short circuits in automotive systems. The device protects against faults through a reliable current limit, which, depending on device variant, is adjustable from 2 A to 25 A .

The high current limit range allows for usage in loads that require large transient currents, while the low current limit range provides improved protection for loads that do not require high peak current. The device is capable of reliably driving various load profiles.

The TPS2HB35-Q1 also provides a high accuracy analog current sense that allows for improved load diagnostics. By reporting load current and device temperature to a system MCU, the device enables predictive maintenance and load diagnostics that improves the system lifetime.

The TPS2HB35-Q1 is available in a HTSSOP package which allows for reduced PCB footprint.

Evaluierungsplatine

HSS-MOTHERBOARDEVM — Highside-Schalter-Hauptplatine

Das HSS-MOTHERBOARDEVM-Evaluierungsmodul wurde zur Evaluierung der Ron-Bausteine von < 50 mΩ im Highside-Schaltersortiment von TI entwickelt. Zu diesen Bausteinen gehören TPS1HA08-Q1, TPS2HB08-Q1, TPS2HB16-Q1, TPS2HB35-Q1 und TPS2HB50-Q1. Diese Platine wird nicht mit den Bausteinen bestückt geliefert, ermöglicht jedoch das Auflöten aller Bausteine auf die Muster-Tochterkarte und die Verwendung in der Hauptplatine. Dieses Benutzerhandbuch beinhaltet die Anschlüsse und eine Beschreibung des Prüfpunkts, den Schaltplan, die Materialliste und das Platinenlayout des EVM.

HINWEIS: DIESE PLATINE WIRD NICHT BESTÜCKT GELIEFERT.   BITTE BEACHTEN SIE DEN JEWEILIGEN PRODUKTORDNER, UM MUSTER DES BAUSTEINS ZU BESTELLEN UND DAS EVM ZU BESTÜCKEN.
