LM5101AM Description

Short technical summary and product information.

The Texas Instruments LM5101AM is a versatile half-bridge gate driver IC. It is engineered to drive both the high-side and low-side N-channel MOSFETs in synchronous buck or half-bridge configurations.

 

Key electrical specifications include a supply voltage range of 9V to 14V, with a high-side bootstrap supply voltage capability up to 118V. The device offers a peak output current of 3A for both high-side and low-side drivers. It features independent control for high and low drivers, non-inverting input logic, and TTL input thresholds. An undervoltage lockout (UVLO) is set at 8V.

 

Performance characteristics include fast propagation times typically 25 ns, with excellent propagation delay matching of 3 ns. The rise and fall times are specified as 8 ns when driving a 1000 pF load. The operating temperature range is -40°C to 125°C (TJ).

 

This gate driver is available in an 8-SOIC surface mount package. Its design makes it suitable for various power converter applications.
