Overview：The DRV8301 is a 6V to 60V gate driver IC for three phase motor drive applications. This device reduces external component count by integrating three half bridge drivers, two current shunt amplifiers, and a switching buck converter. The DRV8301 provides overcurrent, overtemperature, and undervoltage protection. Fault conditions are indicated through the nFAULT and nOCTW pins in addition to the SPI registers.
Features: The power supply voltage range is 6-60v. CurrentCapability comes with 1.7-A source and 2.3-A sink door driver. The product can also reduce electromagnetic interference variable speed control. The product features a guide door drive with 100% cycle support. There are 6 or 3 pwm input modes to choose from. The DRV8301 dual integrated current shunt amplifier has adjustable gain and offset. With integrated 1.5 a Buck converter. Supports 3.3 v and 5 v interfaces And SPI.
Protection functions: DRV8301 has the following protection functions. Programmable dead time control (DTC), programmable overcurrent protection (OCP), PVDD and GVDD undervoltage lockout (UVLO), GVDD overvoltage lockout (OVLO), overtemperature warning/shutdown (OTW/OTS), and reporting via nFAULT, nOCTW, and SPI registers. These functions can better ensure your safety when using this product.
3 Phase Gate Driver：The half bridge drivers use a bootstrap configuration with a trickle charge pump to support 100% duty cycle operation. Each half-bridge is configured to drive two N-channel MOSFETs, one for the high-side and one for thelow-side. The half-bridge drivers can be used in combination to drive a 3-phase motor or separately to drivevarious other loads.
Current Shunt Amplifiers：To minimize DC offset and drift overtemperature, a calibration method is provided through either the DC_CAL pin or SPI register. When DC calibration is enabled, the device will short the input of the current shunt amplifier and disconnect the load. DC calibration can be done at any time, even during MOSFET switching, because the load is disconnected.
