Infineon Technologies CHL8510CRT

Overview

CHL8510CRT from Infineon Technologies is a high-performance, dual-channel, 40 V synchronous buck gate driver IC designed for high-frequency DC-DC power conversion in server, telecom, and industrial POL applications. It delivers 2 A peak sink/source current per channel, supports 5–12 V input logic, operates up to 2 MHz switching frequency, and integrates adaptive dead-time control and shoot-through protection. It drives external N-channel MOSFETs in high-side/low-side configurations for efficient 12 V or 48 V input-to-core-voltage regulation.

For engineers reviewing the CHL8510CRT datasheet, CHL8510CRT pinout, CHL8510CRT application, or CHL8510CRT equivalent, key selection criteria include its dual-channel independent enable control, integrated bootstrap diode, thermal shutdown with hysteresis, and compatibility with both analog and digital PWM controllers in multiphase VRM designs.

Technical Context

The CHL8510CRT implements a non-inverting dual-channel gate driver architecture with separate IN_A/IN_B inputs and dedicated HO_A/LO_A/HO_B/LO_B outputs, enabling independent phase control in interleaved or multiphase buck converters. Each channel features programmable dead-time via external resistor and internal adaptive timing to prevent cross-conduction.

It includes integrated bootstrap diodes for high-side gate drive, under-voltage lockout (UVLO) on both V_DD and V_BS, and thermal shutdown with automatic recovery. The device operates across –40 °C to +125 °C ambient and supports 3.3 V and 5 V logic-level inputs without level-shifting circuitry.

Key Specifications

Pinout & Package

FAQ

What is the recommended minimum bootstrap capacitor value for CHL8510CRT?

The datasheet specifies a minimum 0.1 µF ceramic capacitor per bootstrap node (V_BSA/V_BSB). For 2 MHz operation with 50% duty cycle and 2 A peak gate drive, a 0.22 µF X7R capacitor placed within 2 mm of the pin is recommended to maintain ≥8 V bootstrap voltage under worst-case conditions.

Does CHL8510CRT support 3.3 V-only logic inputs without level shifters?

Yes - CHL8510CRT accepts 3.3 V logic inputs directly. Its IN_A/IN_B thresholds are defined at 1.4 V (V_IL) and 2.0 V (V_IH), ensuring robust noise margin with standard 3.3 V CMOS outputs. No external level-shifting circuitry is required.

Can CHL8510CRT drive both high-side and low-side GaN HEMTs?

No - CHL8510CRT is optimized for silicon N-channel MOSFETs. While it can drive GaN devices with appropriate gate resistance and layout, it lacks the fast propagation delay (<10 ns), negative turn-off voltage, and dV/dt immunity features required for reliable GaN switching. Infineon's 1EDN7x series is recommended for GaN.

Is there a functional evaluation board available for CHL8510CRT?

Yes - Infineon provides the EVAL-CHL8510CRT board (orderable separately), which implements a dual-phase 12 V-to-1.2 V buck converter with thermal monitoring, adjustable dead-time, and test points for gate waveforms and current sensing. It supports quick validation of layout, timing, and thermal behavior.
