Product details

It operates from a 9V to 14V supply rail and can drive the high-side FET using a bootstrap supply rated to 118V maximum. The non-inverting input logic thresholds are 0.8V (VIL) and 2.2V (VIH), making it compatible with 3.3V and 5V controller outputs. It comes in a 10-WDFN exposed-pad package (also designated 10-WSON, 4x4mm) and is rated for junction temperatures from -40°C to 125°C, suiting industrial motor drives, DC-DC converters, and automotive power stages that see under-hood thermal cycling.

If you are qualifying this for a multi-year production run, the active status gives you runway to dual-source or stock a last-time-buy later if the situation changes.

The 9V to 14V supply range on the LM5102SD/NOPB is the bias voltage for the driver itself, not the power stage DC bus. The high-side driver is bootstrapped, and the bootstrap pin can handle up to 118V referenced to ground. That 118V ceiling sets the maximum DC-link voltage for the half-bridge: if your bus runs at 100V nominal, you have 18V of headroom. For a 12V input, 48V output converter or a 24V motor drive, this driver is a solid fit; for a 400V bus you would need a different bootstrap rating.

Package and thermal handling for the 10-WSON

The 10-WDFN exposed pad (4x4mm WSON) requires a thermal land pattern with via stitching to the ground plane. Without adequate thermal vias, the junction temperature can exceed the 125°C rating under continuous 1.6A gate-drive pulses.
