With the integration of two low-dropout regulators, a current-sense amplifier and protection features, the DRV8701 brushed DC gate driver is said to allow designers to replace up to 45 components with a single device to reduce board footprint by 40% compared to competitive solutions.
With a 5.9 to 45V motor-supply supporting 12 and 24V supplies, the DRV8701 gives designers the flexibility to choose their external FETs and scale the gate-drive current to adjust the FET slew rate, optimise system electromagnetic interference performance and eliminate the need for external resistors/capacitors.
On-chip protection includes under-voltage lockout, overcurrent shutdown, short circuit protection, as well as more advanced features to protect external FETs.
