D5T100AJ Double Channel High-Side Driver IC - 100mΩ Automotive Power Switch with Current Sense
D5T100AJ Automotive-Grade High-Side Power Driver for 24V Systems
This double channel high-side smart power switch is specifically designed for 24V automotive applications, offering a robust and highly reliable solution for driving resistive and inductive loads in body control modules, engine management, and lighting systems.
Wide Operating Voltage and 24V Optimization
Supporting a broad supply voltage range from 8V to 36V, this device is fully compatible with 24V vehicle electrical architectures. The integrated overvoltage clamp protects against low energy spikes, ensuring stable operation in harsh automotive environments.
Low On-Resistance for High Efficiency
With a typical on-state resistance (RDS(ON)) of just 100mΩ per channel, the D5T100AJ minimizes power dissipation and heat generation. Each channel supports a continuous load current up to 16A, with a peak current limit of 22A, providing ample headroom for demanding loads.
Analog Current Sense Diagnostic Feedback
The device integrates an analog current sense output that delivers a current proportional to the load current, enabling precise real-time load monitoring. Fault conditions such as overload, overtemperature, open-load, and short-to-VCC are reported via the current sense pin, simplifying system-level diagnostics.
Comprehensive Protection Suite
Designed for maximum reliability, the D5T100AJ incorporates multiple protection features: undervoltage shutdown, overvoltage clamp, load current limitation, thermal shutdown with latch-off, and protection against loss of ground or VCC. Overload and short-to-ground events trigger a latch-off, with reset capability via the fault reset standby pin.
AEC-Q100 Qualified for Automotive Use
Fully qualified to AEC-Q100 standards, this driver operates reliably across the full automotive temperature range of -40°C to +150°C. Its very low standby current and 3.0V CMOS compatible inputs make it suitable for modern power-efficient designs.
Surface-Mount PowerSSO-12 Package
Housed in a 12-pin PowerSSO package, the D5T100AJ supports automated PCB assembly and offers optimized thermal performance for dense ECU layouts.
