2EDL5023U2DXTMA1 Overview
A gate driver IC is a power management semiconductor that sits between a low-power control circuit (such as a microcontroller or PWM controller) and the power MOSFETs, IGBTs, or GaN switches in a switching power converter. By providing high peak current and level-shifting the control signal to the high-side switch referenced to the switching node (SW), gate drivers allow low-voltage controllers to operate power devices stacked in half-bridge or full-bridge topologies. The 2EDL5023U2DXTMA1 belongs to the half-bridge driver category within the broader gate-driver hierarchy: half-bridge driver > gate driver > power management IC > semiconductor.
Key features of the 2EDL5023U2DXTMA1 include 120 V bootstrap voltage rating supporting high-side operation up to 100 V bus rails, integrated bootstrap diode architecture (U2 family), under-voltage lockout (UVLO) on VDD, 3 A typical peak gate drive capability, and matched propagation delay between the high-side and low-side channels to prevent duty-cycle distortion. The PG-TSNP-12-5 package provides a small footprint suitable for space-constrained PCB designs, while the exposed pad supports thermal dissipation of internal driver losses.
The device uses Infineon's proven high-voltage level-shifter technology with integrated bootstrap diode, eliminating the need for an external bootstrap diode in most applications. The EN pin allows external shutdown for low quiescent current standby, important for battery-powered and energy-conscious designs. TTL-compatible inputs allow direct interfacing with 3.3 V or 5 V microcontrollers without level translation.
Typical applications include driving the high-side and low-side MOSFETs in buck, boost, and half-bridge DC-DC converters, motor driver half-bridges up to 100 V bus, Class-D audio amplifier output stages, and primary-side driven switch-mode power supplies. The 3 A peak current and 120 V bootstrap rating make this part particularly suited for higher-power synchronous rectification stages.
When designing with the 2EDL5023U2DXTMA1, ensure that the bootstrap capacitor value is sized for the gate charge requirement and switching frequency of the driven MOSFET, with a 100 nF to 1 uF ceramic typically sufficient. Place the driver close to the driven power switches to minimize gate-loop inductance and avoid ground bounce by using a low-impedance VSS return. A TVS or snubber on the switching node may be required in motor-drive applications with high dV/dt.

Typical Applications
2EDL5023U2DXTMA1 is suitable for 6 applications: Synchronous Buck DC-DC Converter, Half-Bridge Motor Driver, Class-D Audio Amplifier Output Stage, Primary-Side Switch-Mode Power Supply (SMPS), Solar Micro-Inverter MPPT Stage, Telecom 48V Point-of-Load (POL) Converter.
Synchronous Buck DC-DC Converter
The 2EDL5023U2DXTMA1 drives the high-side and low-side MOSFETs in a synchronous buck converter, where its 120 V bootstrap rating supports input rails up to 100 V and its 3 A peak current enables fast switching of mid-current MOSFETs. According to the Infineon datasheet, the matched propagation delay between HI and LI channels prevents duty-cycle distortion at high switching frequencies. Compared to discrete bootstrap designs, the integrated bootstrap diode eliminates one external component and reduces PCB area. The 5 V VDD supply is typically derived from a small auxiliary linear regulator.

Key Differentiators
- 120 V bootstrap with integrated bootstrap diode (vs IRS2004STRPBF)
- 3 A peak gate drive current in compact PG-TSNP-12-5 (vs 2EDN7434RXTMA1)
- 120 V bootstrap optimized for 48-100 V bus applications (vs 2EDL6014ACG2DXTMA1)
Design Notes
The bootstrap capacitor (CBOOT) on pin HB must be sized to hold sufficient charge for one full switching cycle. Estimated: for Qg_total of 50 nC and switching frequency 100 kHz, CBOOT >= Qg_total / dV ~= 50nC / 0.1V = 0.5 uF minimum. According to the Infineon datasheet, 100 nF to 1 uF X7R ceramic is typical; ensure the bootstrap diode refreshes CBOOT within the low-side on-time. Add a small ceramic bypass (10-100 nF) on VDD close to the IC.
Place the 2EDL5023U2DXTMA1 within 5-10 mm of the power MOSFETs it drives to minimize gate-loop inductance. Use a wide, short gate trace and a ground return path directly to the VSS pin, avoiding sharing the ground return with high-current switching loops. According to the Infineon datasheet, the exposed thermal pad must be soldered to a copper pour to provide adequate thermal dissipation of internal driver losses.
Do not exceed the 120 V bootstrap voltage rating on pin HB - even brief overvoltage transients from inductive load switching can permanently damage the high-side level-shifter. According to the Infineon datasheet, add a TVS diode or RC snubber on the switching node (pin SW) to clamp transients. Also ensure the EN pin is not left floating if not used; tie it to VDD through a 10 kohm resistor if a controller does not drive it directly.
