Overview

The TPM81530 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 TPM81530 series is isolated from its two output drivers by a reinforced isolation barrier rated at 5 kVRMS, providing a typical of 125 kV/μs 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, which when set to high, simultaneously shuts down both outputs. The DISABLE pin is internally pulled up, so it must be tied to ground 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.

The device has integrated Miller Clamp to prevent false turn-on by Miller current.
