Diodes Adds Hall Sensors and IntelliFET Switches for Automotive

What happened

Diodes Incorporated has introduced new current-sensing and power-switching devices for automotive applications, comprising the AHC1724Q and AHC1725Q Hall effect current sensors and three second-generation IntelliFET high-side switches: the ZXMS81030SPQ, ZXMS82030S14PQ and ZXMS82045S14PQ. The two sensors provide galvanically isolated AC and DC current measurement for electric vehicle onboard chargers (OBCs), charging stations and other power systems, with measurement ranges up to ±50 A, a typical primary conductor resistance of 1.2 mΩ, a maximum working voltage of 420 VDC for basic isolation according to UL 62368-1, 120 kHz bandwidth, a typical response time of 4.0 µs and a typical propagation delay of 2.0 µs. The AHC1724Q operates from 4.5 V to 5.5 V and supports ranges from ±2.5 A to ±50 A, while the AHC1725Q uses a 3.0 V to 3.6 V supply and covers ±5 A to ±50 A; both are housed in a low-profile SO-8 (Type CJ2) package and operate from -40°C to +150°C, with standard-compliant AHC1724 and AHC1725 versions also available for industrial and commercial applications. The three IntelliFET devices, targeting 12 V automotive loads, combine a vertical DMOS N-channel MOSFET with an integrated controller, managing inrush current and protecting against short circuits, overvoltage, load-dump conditions, overtemperature with automatic restart and ESD; the single-channel ZXMS81030SPQ comes in an SO-8EP package, while the dual-channel ZXMS82030S14PQ and ZXMS82045S14PQ use SO-14EP packages, both types with exposed underside heatsinks. Diodes is showcasing the devices at electronica 2026, where the IntelliFET devices are part of a 48 V power-tree demonstration at Booth 211 in Hall C6, providing a protected, switched 12 V output.
