The A6862 is an n-channel power MOSFET driver capable of controlling MOSFETs connected as a 3-phase solid-state relay in phase-isolation applications. It has three independent floating gate drive outputs to maintain the power MOSFETs in the on-state over the full supply range with high phase-voltage slew rates. An integrated charge pump regulator provides the above battery supply voltage necessary to maintain the power MOSFETs in the on-state continuously when the phase voltage is equal to the battery voltage. The charge pump will maintain sufficient gate drive (>7.5 V) for battery voltages down to 4.5 V with 100 kΩ gate source resistors.
The three gate drives can be controlled by a single logic-level input. In typical applications, the MOSFETs will be switched on within 8 μs and will switch off within 1 μs.
Two independent activation inputs can be used to put the A6862 into a low-power sleep mode with the charge pump disabled. Undervoltage monitors check that the pumped supply voltage and the gate drive outputs are high enough to ensure that the MOSFETs are maintained in a safe conducting state.
The A6862 is supplied in a 16-lead TSSOP (LP) with exposed pad for enhanced thermal dissipation. They are lead (Pb) free, with 100% matte-tin leadframe plating.
