Single channel low-side drivers integrate robust protection features

Infineon Technologies expands its µHVIC family of integrated circuits for high and low voltage: the single channel low-side drivers IR44252L, IR44272L and IR44273L enable robust and cost effective design solutions. The device family utilises Infineon’s proven, robust high voltage junction isolation (HVJI) technology to realise multiple functions and integrate robust protection features.

The driver ICs are packaged in a small 5-lead SOT23 and are complementary with other µHVIC parts. The devices offer a cost effective and easy-to-implement solution for flexible PCB layouts across many platforms and applications.

In addition to the tiny SOT23 packages, the single channel low-side drivers feature a wide V _cc range of 5 V to 20 V, an enable input (IR44272L) and dual output pins (IR44252L, IR44273L). The typical source current and sink current of the IR44252L is specified with 300 and 550mA, 1.7/1.5A for the IR44272L and IR44273L, respectively.

The low-side drivers offer V _CC Under Voltage Lock Out (UVLO) protection and fast switching. Typical turn-on and turn-off propagation delay is 50ns and typical turn-on rise time and turn-off fall time down to 10ns (IR44273L, IR44272L). The devices are 3.3V logic compatible and provide CMOS Schmitt-triggered inputs.
