Infineon – EiceDRIVER™ 1ED44176N01F – 25 V single-channel low-side gate drivers with over-current protection

1ED44176N01FXUMA1

The 1ED44176N01F expands the low-side gate driver portfolio targeting single-ended topologies such as digitally controlled power factor correction (PFC) in home appliances like residential air-conditioning.
It is a 25 V low-voltage single-channel low-side non-inverting gate driver for MOSFET and IGBT with a typical +0,8 A source and -1,75 A sink currents in a small 8-lead PG-DSO8 package. The 1ED44176N01F provides cost and space savings by integrating the comparator.

Features:
– Over-current detection with positive voltage input
– 0.5 V Over-current threshold with accurate ±5% tolerance
– 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
– Separate logic and power ground
– 2 kV ESD HBM

Benefits:
– Up to 50% space savings and 20% cost savings compared to the discrete components
– Flexible fault clear time setup makes it easy to adjust to different microcontroller processing speeds
– Minimizes power consumption
– Avoids noise coupling from output to input to improve noise immunity
– Eliminates switching loss at low VCC supply voltage

Competitive advantage:
– Single-channel low-side gate driver that integrates over-current protection with fault reporting and enable functionality
– Saves up to ~20% cost and ~50% space in the design
– Lowest OCP threshold tolerance (±5%) for accurate current sensing
– To be used in any application requiring overcurrent protection
