LM2x0x Product Overview

The LM2x0x devices are a family of low current half-bridge drivers optimized to drive MOSFETs and IGBTs in industrial applications where BOM costs are very sensitive and power density is critical. The family has five generic parts, most of which are available in a smaller 2mm × 2mm package. This product overview highlights the benefits that this family of devices can provide to your system.

Optimized

LM2x0x features a 0.5A/0.8A drive current to reduce switching losses and improve overall efficiency in lower power systems. This combined with the small WSON package options available make the LM2x0x one of TI’s smallest half-bridge drivers. The family keeps the feature offerings simplistic, reducing the number of orderables and streamlines the selection process.

Robust

The LM2x0x 107V_HB and -19.5V negative transient handling allows the proper headroom and buffer for the driver to exist and operate in noisy environments without the need for external components.

Features

The LM2x0x family offers a range of features that expand the potential use cases. UVLO options allows designers to choose a voltage level that maintains that FETs remain open when there is not enough potential for the FET to be charged. Inverting input or shutdown features give designers flexibility in implementation and reduces external circuitry needed to implement the driver best for their system.
