1ED44175N01BXTSA1 Overview
A low-side gate driver is a power-management IC placed between a low-voltage control signal (typically 3.3 V or 5 V logic from a microcontroller) and the gate of a switching power transistor referenced to ground. Its role in the broader system hierarchy is: gate driver -> driver IC -> power management IC -> semiconductor. Low-side drivers are the simplest and most economical drivers and are widely used when the gate of the power device can be referenced to the same ground as the control logic, simplifying isolated power supply design.
Key features of the 1ED44175N01BXTSA1 include 2.6 A typical source/sink drive current for fast switching, a wide logic-input threshold compatible with standard CMOS or LSTTL outputs, an integrated OCP comparator pin for current-sense feedback, an open-drain FAULT output for system diagnostics, and a dedicated EN pin for power sequencing. The non-inverting topology means the output follows the input logic level directly.
The internal architecture uses a robust monolithic construction with a current buffer output stage optimized for high dV/dt immunity. The OCP function compares an external current-sense voltage against an internal reference, providing rapid fault response that helps protect the power switch from short-circuit conditions. The device operates from a single supply rail, simplifying PCB layout.
Typical applications include low-side driving of IGBTs and MOSFETs in motor-control half-bridges, switch-mode power supply (SMPS) primary-side switches, induction-heating inverters, and general-purpose power converters where fault protection is required. It pairs naturally with Infineon IGBTs such as the IKD15N60RFATMA1 and CoolMOS MOSFETs.
When designing with the 1ED44175N01BXTSA1, ensure the OCP sense resistor and reference network are properly scaled to the trip threshold and that the FAULT pin is correctly pulled up. The PG-SOT23-6-3 package has limited power dissipation, so for high-frequency high-current applications the thermal performance should be validated.

Typical Applications
1ED44175N01BXTSA1 is suitable for 6 applications: Low-Side IGBT Drive in Motor Control, Switch-Mode Power Supply Primary-Side Switch Driver, Induction Heating Inverter Low-Side Driver, Battery Management System Power-Path Switching, Class-D Audio Amplifier Output Stage Driver, Industrial Solenoid and Relay Driver.
Low-Side IGBT Drive in Motor Control
The 1ED44175N01BXTSA1 drives the low-side IGBT of a half-bridge in variable-frequency drives and small motor inverters. Its 2.6 A source/sink current produces fast switching edges that reduce switching losses in the IGBT, while the integrated OCP comparator monitors the shunt resistor between the low-side emitter and ground to detect short-circuit desaturation within microseconds. In typical 600 V/10 A IGBT designs such as the IKD15N60RFATMA1, the driver pulls the gate from 0 V to 15 V in tens of nanoseconds, keeping the diode reverse-recovery and turn-on losses low. The FAULT pin is wired to the microcontroller interrupt, shutting down PWM within one switching cycle on over-current.
Recommended
Switch-Mode Power Supply Primary-Side Switch Driver
In isolated AC-DC and DC-DC converters, the 1ED44175N01BXTSA1 drives the primary-side MOSFET or low-voltage IGBT of the power stage. Its 25 V VCC rating supports standard 12 V gate-drive rails, and the 2.6 A peak drive current charges and discharges the MOSFET's gate capacitance quickly, reducing transition losses at switching frequencies up to several hundred kHz. The integrated OCP pin can be wired to the current-sense transformer or shunt, providing cycle-by-cycle current limiting that complements the controller's protection. The compact PG-SOT23-6-3 footprint is ideal for the dense layout of a small flyback or forward converter auxiliary supply.
Recommended
Induction Heating Inverter Low-Side Driver
Induction-heating inverter topologies use resonant half-bridges operating at 20-100 kHz where switching losses dominate. The 1ED44175N01BXTSA1 is well suited to drive the low-side IGBT in such inverters because its 2.6 A drive current can source and sink the gate charge of a 600 V/30 A-class IGBT within tens of nanoseconds. The integrated OCP pin connects to a current-sense resistor or shunt, protecting the resonant tank from over-current conditions during load transients. The PG-SOT23-6-3 package keeps driver parasitics low and helps achieve the clean switching waveforms needed for efficient induction heating.
Recommended
Battery Management System Power-Path Switching
Battery-management systems (BMS) for e-mobility and energy storage require low-loss power-path switching with robust protection. The 1ED44175N01BXTSA1 can drive low-side MOSFETs that disconnect the battery pack from the load on fault. Its 2.6 A drive current enables fast turn-off of high-current MOSFETs, limiting the let-through energy during a short-circuit, and the integrated OCP pin provides direct current-sense feedback for fast fault response. The 6-pin SOT-23-6-3 package fits on small BMS daughter boards where space is at a premium, and the FAULT pin interfaces directly to the BMS controller's interrupt line.

Class-D Audio Amplifier Output Stage Driver
Class-D audio amplifiers benefit from the 1ED44175N01BXTSA1's 2.6 A drive current and integrated protection when driving the low-side MOSFET of the output half-bridge. The fast gate transitions reduce dead-time and therefore distortion, while the OCP function provides instant protection against the output short-circuit to the speaker or to the supply rail. The compact PG-SOT23-6-3 package fits on the amplifier's output stage PCB alongside the output inductors. Combined with a high-side driver such as the IR2109SPBF, the 1ED44175N01BXTSA1 enables a complete half-bridge driver solution with cycle-by-cycle current limiting.
Recommended
Industrial Solenoid and Relay Driver
Industrial solenoid and relay drivers benefit from the integrated OCP and FAULT features of the 1ED44175N01BXTSA1. The driver can switch the low-side of a 24 V solenoid or relay coil, with the OCP pin detecting over-current conditions caused by coil short circuits or mechanical jamming. The 25 V VCC rating matches typical 24 V industrial rails, and the 2.6 A drive current can handle most small-to-medium solenoids directly. The FAULT output can be wired to the PLC's digital input to flag the fault to the controller, enabling predictive maintenance and reducing machine downtime.

Design Notes
Estimated: At 25 V VCC, 2.6 A peak drive current, and 100 kHz switching, the average gate-driver dissipation is approximately P = Qg x VCC x fsw. For a typical 50 nC IGBT gate charge, P = 50e-9 x 25 x 100e3 = 0.125 W. The PG-SOT23-6-3 package easily handles this level, but designers should still connect the exposed pad to a copper pour for improved thermal spreading. The VCC bypass capacitor should be at least 1 uF ceramic placed within 5 mm of the VCC pin to provide the high peak currents during gate transitions.
The OCP pin is an analog comparator input, not a digital input. Per the Infineon datasheet, the OCP sense voltage threshold is internal; do not drive this pin above VCC. Use a low-impedance current-sense resistor or shunt and place a small RC filter (typically 1 kohm + 100 pF) close to the OCP pin to reject switching noise. The FAULT output is open-drain and requires an external pull-up resistor (typically 10 kohm to VCC) to a logic-compatible rail. Do not leave FAULT floating; otherwise the fault indicator will not propagate to the controller.
Route the gate-drive loop (OUT, GND, gate, source of power device) as a tight, low-inductance loop to minimize ringing and overshoot. Keep the gate-driver placed within 10 mm of the power switch to limit parasitic loop inductance. Use a ground plane on the driver side of the PCB and avoid splitting the ground between signal and power sections. Place the OCP sense components and bypass capacitors on the same layer as the driver to minimize vias in the high-current paths.
According to the Infineon datasheet, the logic input (IN pin) is compatible with standard CMOS/LSTTL levels. To avoid false triggering in noisy environments, place a small RC filter (typically 100 ohm + 100 pF) close to the IN pin to debounce the input signal. Maintain short, impedance-controlled traces from the controller to the IN pin, especially in motor-drive applications where dV/dt coupling can induce ground bounce. The EN pin has an internal pull-down; do not float it unintentionally or it may drift and cause spurious enable/disable events.
