Half-bridge gate driver for 12 V industrial and automotive rails
The Texas Instruments LM5101BSDX/NOPB is a half-bridge gate driver for two N-channel MOSFETs. It delivers 2 A peak source and sink current. The bootstrap diode supports a high-side voltage up to 118 V. Supply range is 9 V to 14 V. The independent channel architecture lets each output be controlled separately.
Package and thermal — 10-WSON with exposed pad
The 10-WSON package (4x4 mm) with exposed pad requires a thermal land on the PCB for adequate heat dissipation. The operating junction temperature range of -40 to 125 °C covers industrial and automotive under-hood environments. For continuous operation at high switching frequency and maximum supply voltage, ensure the PCB copper area under the pad connects to a sufficient ground plane to keep junction temperature within limits.
Lifecycle and sourcing — active, no LTB pressure
The LM5101BSDX/NOPB is listed as Active with ROHS3 compliance. This part is suitable for new designs and production BOMs without obsolescence risk in the near term.
