The LTC7068 is a half-bridge dual N-Channel MOSFET gate driver that operates at up to 150V input voltage and features a supply-independent three-state pulse width modulation (PWM) input logic.
The strong 1.3Ω pull-down and 1.6Ω pull-up drive capability can drive large gate capacitances of high voltage MOSFETs with short transition times in high switching frequency applications. The adaptive shoott-through protection is designed for optimized efficiency and MOSFET cross-conduction protection.
The LTC7068 contains undervoltage lockout (UVLO) circuits on both the V CC supply and floating driver supply that turn off the external MOSFETs when activated.
Applications
- Industrial Power Systems
- Half-bridge DC/DC Converters
- Telecommunication Power Systems
