It operates from a 9V to 14V supply rail and can drive the high-side FET using a bootstrap supply rated to 118V maximum. Each output delivers 1.6A peak source and sink current, with typical rise and fall times of 600ns. 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. ## Active lifecycle — no LTB pressure on this BOM line The LM5102SD/NOPB carries an Active product status per the manufacturer, with ROHS3 compliance. The 10-WSON package is a standard footprint that multiple distributors stock; sourcing through independent channels remains straightforward. 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. ## Bootstrap voltage and supply range — what they mean for your power stage 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. The 1.6A peak gate drive is enough to switch medium-power MOSFETs with moderate gate charge (tens of nC) at switching frequencies up to a few hundred kilohertz, but the 600ns rise/fall time is slower than many modern drivers — expect higher switching losses than a sub-100ns part, but also lower EMI. 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. The exposed pad is the main heat path; the datasheet layout recommendation should be followed.","metaTitle":"LM5102SD/NOPB Half-Bridge Gate Driver, 1.6A, 9V-14V, 10-WSON","metaDescription":"LM5102SD/NOPB half-bridge N-channel MOSFET gate driver. 1.6A peak output, 9V-14V supply, bootstrap to 118V.
