Infineon – EiceDRIVER™ 1ED44175N01B

Infineon Technologies expands its low-side gate driver portfolio with 1ED44175N01B – a 25 V, single-channel low-side gate driver with integrated over-current protection (OCP), fault reporting, and enable functionality.
OCP is typically implemented using a current measurement circuit with a comparator such as LM293 and a network of resistors and capacitors. 1ED44175N01B can provide up to 20 percent cost and 50 percent space savings by integrating the OCP comparator, which features an accurate current sensing threshold tolerance of ±5 percent. In addition, 1ED44175N01B combines fault output reporting to the controller and driver enable functionality on the same pin. This dual functioning pin allows for a compact IC design to fit into a tiny PG-SOT23 6-pin package.

Features
– 0.246 V over-current threshold with accurate ±5% tolerance
– Over-current detection with negative voltage input
– Single pin for fault output and enable
– Programmable fault clear time
– Under voltage lockout
– CMOS Schmitt-triggered inputs
– 3.3 V, 5 V and 15 V input logic compatible
– Output in phase with input
– -10 Vdc negative Input capability of OCP pin
– 3 kV ESD HBM

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

Target applications
– Home appliances
– Room air conditioners
– Refrigerators
– Small home appliances
– Induction cooker
– Induction rice cooker
– Microwave oven
– Power supplies (SMPS)

Competitive advantage
– 1ED44175N01B is the only low-side gate driver with integrated overcurrent protection in a tiny SOT23 6-pin package.
– OCP threshold tolerance of ±5% provides accurate sensing com-pared to other gate drivers with integrated overcurrent protection.
