Product details

Peak current and switching speed — what they mean for the BOM

The 3A source / 4.5A sink peak current rating determines which MOSFET gate charge this driver can switch within the target dead time. The non-inverting input keeps logic simple: one PWM signal drives both gates with internal dead-time generation. Supply range of 4 V to 6.85 V means the driver bias rail is separate from the power stage.

Temperature grade and deployment environment

Rated for -40°C to 125°C junction temperature, this driver fits industrial motor drives, outdoor telecom rectifiers, and under-hood automotive auxiliary converters. The 8-SOIC package keeps board area small but watch thermal dissipation if driving high-frequency, high-gate-charge MOSFETs near the upper temperature limit.

Lifecycle and sourcing reality

It can be committed to new designs without obsolescence risk.

Frequently asked questions

What is a suitable equivalent or replacement for LM27222M-TI?

A close functional peer is the LM5106MM/NOPB, also a half-bridge N-channel MOSFET driver with non-inverting input. The LM5106 runs from an 8 V supply and delivers 1.2 A peak output — lower drive strength than the LM27222M-TI's 3A/4.5A. Check gate charge requirements before substituting.

What are typical applications for LM27222M-TI?

Typical applications include synchronous buck converters, half-bridge power supplies, and DC-DC modules in industrial, telecom, and automotive auxiliary power stages.

Can I use LM27222M-TI with a 3.3V logic input?

The input type is non-inverting, and the supply range is 4 V to 6.85 V. The logic threshold scales with supply; at 5 V bias, a 3.3 V logic high may not reliably cross the input threshold. Level-shift or use a 5 V logic source for guaranteed operation.
