Applications
The DRV8300 is used in three-phase BLDC motor drive systems for industrial fans, pumps, compressors, and servo drives where external MOSFETs are selected to match specific power and thermal requirements. It targets e-bike controllers, power tools, and robotic joint actuators operating from 12 V to 48 V battery systems needing flexible gate drive with integrated protection. Its wide supply range and 1 A gate current make it suitable for driving low-RDS(on) MOSFETs in high-efficiency motor inverters.

Frequently Asked Questions
What gate drive current does DRV8300 provide for driving external MOSFETs in a BLDC motor inverter?
The DRV8300 provides 1 A source and 1 A sink gate drive current per channel, enabling fast switching of external N-channel MOSFETs with gate charge up to several hundred nanocoulombs. At 1 A drive and a 20 nC gate charge MOSFET, rise and fall times are approximately 20 ns, reducing switching losses in 48 V BLDC motor drive applications.
What supply voltage range does DRV8300 support, and is it compatible with 48 V e-bike battery systems?
The DRV8300 operates from 6 V to 60 V VM supply, making it fully compatible with 12 V, 24 V, and 48 V battery systems. For a 48 V nominal e-bike battery that may reach 54 V fully charged, the 60 V rating provides adequate margin. The wide range allows the same DRV8300 design to be reused across multiple motor voltage platforms.
How does the integrated bootstrap circuit in DRV8300 simplify high-side MOSFET gate drive design?
The DRV8300 integrates a bootstrap diode and charges the external bootstrap capacitor automatically during the low-side MOSFET on-time, eliminating the need for a separate isolated high-side gate drive power supply. A 100 nF bootstrap capacitor per phase is sufficient to supply gate charge for most 60 V-rated MOSFETs, simplifying the PCB layout and reducing BOM cost compared to transformer-isolated drive solutions.
What protection features does DRV8300 include to safeguard the motor drive power stage?
The DRV8300 includes overcurrent protection (OCP) that latches off the gate outputs when MOSFET drain current exceeds the programmed threshold, overtemperature shutdown (OTS) at approximately 150°C junction temperature, and undervoltage lockout (UVLO) that disables switching if VM drops below the safe operating threshold. These protections prevent MOSFET damage during fault conditions such as motor stalls or short-circuit events.
