Key Features
- 3-phase BLDC gate driver with 0.5 A peak gate drive current per channel enables fast switching of external MOSFETs for efficient motor control
- Integrated protection features including overcurrent, undervoltage lockout, and thermal shutdown reduce external component count and protect the power stage
- 48-pin TQFP package provides ample I/O for Hall sensor inputs, PWM control, fault signaling, and SPI or analog interface to a host microcontroller
- Supports both sensored (Hall effect) and sensorless BLDC motor control topologies for flexible motor selection in industrial and consumer designs
Applications
The MCP8026T-115H/PT is designed for compact BLDC motor drive systems in appliances, power tools, and industrial fans where a single gate driver IC must interface between a microcontroller and three pairs of external power MOSFETs. HVAC blower motors, compressor drives, and robotic joint actuators benefit from its integrated fault protection and Hall sensor interface, which simplify the control board design. Consumer electronics such as cordless vacuum cleaners and e-bike controllers also leverage its 48-pin TQFP footprint to consolidate gate drive, current sensing, and fault reporting into one package.

Frequently Asked Questions
What is the peak gate drive current of the MCP8026T-115H/PT and how does it affect MOSFET switching speed?
The MCP8026T-115H/PT provides 0.5 A peak gate drive current per channel. Higher gate current charges MOSFET gate capacitance faster, reducing switching transition times and lowering switching losses in the 3-phase bridge. This is especially important for motors operating at PWM frequencies above 20 kHz where fast switching maintains efficiency.
Which motor control topologies are supported by the MCP8026T-115H/PT for BLDC drive systems?
The device supports both Hall-effect sensored and back-EMF sensorless commutation topologies for 3-phase BLDC motors. Sensored mode uses 3 digital Hall inputs to determine rotor position, while sensorless mode uses zero-crossing detection of back-EMF voltages, allowing designers to select the most cost-effective motor type for their application.
What built-in protection does the MCP8026T-115H/PT provide to safeguard the external power MOSFETs?
The MCP8026T-115H/PT integrates undervoltage lockout (UVLO) that disables gate outputs when supply voltage drops below the safe threshold, overcurrent detection that shuts down the drive within microseconds of a fault, and thermal shutdown that protects the IC above approximately 150°C junction temperature. These features prevent MOSFET damage without requiring additional discrete protection circuits.
How does the 48-pin TQFP package of the MCP8026T-115H/PT simplify motor drive board layout compared to discrete gate drivers?
The 48-pin TQFP with 0.5 mm pitch integrates gate drive channels for all 6 switches (high-side and low-side for 3 phases), Hall sensor inputs, fault outputs, and control interface pins into a single 7 mm x 7 mm body. This consolidation reduces PCB layer count and trace routing complexity compared to using 6 discrete gate driver ICs, cutting board area by 50% or more.
