8.1 Application Information
The DRV8302 is a gate driver designed to drive a 3-phase BLDC motor in combination with external power
MOSFETs. The device provides a high level of integration with three half-bridge gate drivers, two current shunt
amplifiers, overcurrent protection, and a step-down buck regulator.
8.1.1 Gate Driver Power Up Sequencing Errdata
The DRV8301 gate drivers may not correctly power-up if a voltage greater than 8.5 V is present on any SH_X
pin when EN_GATE is brought logic high (device enabled) after PVDD1 power is applied (PVDD1 > PVDD_UV).
This sequence should be avoided by ensuring the voltage levels on the SH_X pins are less than 8.5 V when the
DRV8301 is enabled through EN_GATE.
