LMG1205
Overview
The LMG1205 is designed to drive both the highside and the low-side enhancement mode Gallium Nitride (GaN) FETs in a synchronous buck, boost, or half-bridge configuration. The device has an integrated 100-V bootstrap diode and independent inputs for the high-side and low-side outputs for maximum control flexibility.
- Independent high-side and low-side TTL logic inputs
- 1.2-A peak source, 5-A sink current
- High-side floating bias voltage rail operates up to 100 VDC
- Internal bootstrap supply voltage clamping
- Split outputs for adjustable turnon, turnoff strength
- 0.6-Ω pulldown, 2.1-Ω pullup resistance
- Fast propagation times (35 ns typical)
- Excellent propagation delay matching (1.5 ns typical)
- Supply rail undervoltage lockout
- Low power consumption
