Low-side driver range for diverse design beyond 1MHz

Fairchild Semiconductor has a broad selection of low-side gate drivers, with 2A- and 4A-rated devices providing flexible choices for designers.

Short and well-controlled internal propagation delays enable switching frequencies above 1MHz. In addition, dualdriver devices feature matched delays between the two channels for applications such as synchronous rectifiers where interchannel timing is critical. Two drivers can also be connected in parallel to effectively double the current capability driving a single MOSFET. All devices have a high maximum operating voltage of 18V for rugged and reliable operation.

Package options include a choice of 2mm x 2mm 6-lead MLP or 5-lead SOT23 packages for single drivers and 3mm x 3mm 8-lead MLP or SOIC-8 packages for dual-driver devices. Designers can also choose from TTL or CMOS input thresholds to optimise circuit compatibility.

For dual-driver ICs, several logic-configuration options are available including inverting or noninverting inputs.
