Product Overview
LT8418ACBZ-R7 is a half-bridge GaN driver with a smart integrated bootstrap switch that integrates top and bottom driver stages, driver logic control, and protections. It can be configured into synchronous half-bridge, full-bridge topologies, or buck, boost, and buck-boost topologies. It also integrates a smart integrated bootstrap switch to generate a balanced bootstrap voltage from VCC with a minimum dropout voltage. It provides split gate drivers to adjust the turnon and turn-off slew rates of GaN FETs to suppress ringing and optimize EMI performance. All driver inputs and outputs have default low-state to prevent GaN FETs from false turn-on. The application includes high-frequency DC-DC switching power converters, half-bridge, full-bridge, push-pull converters, data centre power supplies, motor drivers, Class-D audio amplifiers, and consumer, industrial, and automotive.
- Operating voltage range from 3.85 to 5.5V (TA = 25°C, VCC = VBST = 5V, VGND = VSW = 0V)
- Quiescent current is 250µA typ (TA = 25°C, VCC = VBST = 5V, VGND = VSW = 0V)
- Smart integrated bootstrap switch, split-gate-driver to adjust turn-on/turn-off strength
- Default low-state for all driver inputs and outputs
- Independent INT, INB inputs with TTL logic compatible
- Undervoltage and overvoltage lockout protections
- Propagation delay matching is 1.5ns (typical)
- Operating current is 2.4mA typ (FSW = 400KHz, TA = 25°C)
- 12-Ball WLCSP package, operating temperature range from -40°C to 125°C
