Infineon – EiceDRIVER™ 25 V, low-side gate driver – 1ED44173N01B

The 1ED4417x family of single-channel low-side gate drivers integrates fast over-current protection (OCP), fault reporting, and enable functionality. 1ED44173N01B is the latest addition to the series with dedicated features for MOSFETs.

1ED44173N01B combines fault output reporting to the controller, adjustable fault clear timer, and driver enable functionality on the same pin (EN/FLT). This multi-functioning pin allows for a compact IC design to fit into a tiny PG-SOT23 6-pin package, enabling a cost-effect solution for implement over-current protection and protecting the power switch

Features
– Overcurrent protection threshold voltage with ±5% tolerance
– Single pin for fault output and enable
– Programmable fault clear time
– 25 V Max VCC supply voltage
– Under voltage lockout (UVLO) protection
– CMOS Schmitt-triggered inputs
– 3.3 V, 5 V and 15 V input logic compatible
– Output in phase with input
– 3 kV ESD HBM
– 6-pin SOT23 package

Benefits
– Integrated over-current protection and single-pin fault output and enable function provide potential space and cost savings
– OCP threshold tolerance of ±5% provides accurate sensing
– Flexible fault clear time set-up
– Under-voltage lock out provides protection at low supply voltage
– Industry standard package

Competitive advantage
– 1ED44173N01B is the only low-side gate driver with fast integrated overcurrent protection in a tiny SOT23 6-pin package.
– OCP threshold tolerance of ±5% provides accurate sensing compared to other gate drivers with integrated overcurrent protection.
– Fast OCP sensing to output driver shutdown of less than 1 us protects low or zero short circuit rated switches
– 25 V maximum supply voltage (VCC max) for increased operating headroom and power supply noise immunity

Target applications
– Home appliances
– Small home appliances
– Power supplies (SMPS)
– Battery Chargers for power tools and outdoor power equipment
