TPM21520

4.2-A Source, 7.8-A Sink, 5.7-kVRMS Dual-Channel Isolated Gate Driver

Overview

The TPM21520 series consists of isolated dual-channel gate drivers that feature 4.2-A source and 7.8-A sink peak current. These drivers are specifically designed to power MOSFETs, IGBTs, and SiC MOSFETs, with ultralow propagation delay and minimal pulse-width distortion.

The input side of the TPM21520 series is isolated from its two output drivers by a reinforced isolation barrier rated at 5.7 kVRMS, providing a typical of 125-V/ns common-mode transient immunity (CMTI). Additionally, the two secondaryside drivers feature internal functional isolation, enabling a working voltage of up to 1500 VDC.

Each driver within the series offers flexible configuration options, functioning as either two low-side drivers, two high-side drivers, or as a half-bridge driver with a programmable dead time. For safety measures, a dedicated disable pin is included. When the pin is set to high, both outputs are simultaneously shut down. Leaving this pin open or grounding, it allows for normal operation. Furthermore, the system incorporates a fail-safe mechanism that forces both outputs to go low in the event of a primary-side logic failure.
