Frequently Asked Questions
What is the maximum supply voltage for the LM5100AM?
The LM5100AM supports a VCC supply range of 4.5V to 15V and a bootstrap (VBS) supply up to 100V, making it suitable for high-voltage power conversion applications such as industrial motor drives and DC-DC converters.
What is the peak gate drive current of the LM5100AM?
The LM5100AM provides 3A peak source and 3A peak sink gate drive current for both the high-side and low-side outputs, enabling fast turn-on and turn-off of power MOSFETs and reducing switching losses in high-frequency circuits.
What are typical applications for the LM5100AM?
Typical applications include synchronous buck converters, half-bridge and full-bridge motor controllers, class-D amplifiers, and industrial power supplies. The bootstrap architecture allows direct drive of floating high-side N-channel MOSFETs without an isolated power supply.
Is the LM5100AM compatible with 3.3V or 5V logic input signals?
Yes, the LM5100AM accepts logic-level input signals compatible with both 3.3V and 5V systems, with a typical input threshold below 2V, making it easy to interface with standard microcontrollers and DSP gate-drive outputs.
