Product Summary

The BTS443P is an N channel vertical power FET with charge pump, current controlled input and diagnostic feedback with load current sense. It is integrated in Smart SIPMOS chip on chip technology. The BTS443P is providing embedded protective functions of the BTS443P. Applications of the BTS443P are: Power switch with current sense diagnostic feedback for 12V and 24 V DC grounded loads, All types of resistive, capacitive and inductive loads (no PWM with inductive loads), Replaces electromechanical relays, fuses and discrete circuits.

Parametrics

BTS443P maximum ratings: (1)Supply voltage: Vbb 36 V; (2)Supply voltage for full short circuit protection: Tj=-40 to 150 ℃Vbb: 24 V; (3)Load dump protection VLoadDump = UA + Vs, UA = 13.5 V RI= 2 Ω, RL= 2.7 Ω, td= 200 ms, IN= low or high; (4)VLoad dump: 60 V; (5)Load current IL: self-limited A ; (6)Operating temperature range Tj: -40 to +150 ℃; (7)Storage temperature range Tstg: -55 to +150 ℃; (8)Power dissipation (DC) TC ≤ 25℃ Ptot 42 W; (9)Inductive load switch-off energy dissipation.
