PMIC - Full, Half-Bridge Drivers

1. Overview

Full and Half-Bridge Drivers are critical components in power management integrated circuits (PMICs), designed to control power transistors in high-side and low-side configurations. These drivers enable precise switching of MOSFETs or IGBTs in power conversion systems, playing a pivotal role in motor control, DC-DC converters, and motorized industrial equipment. Their ability to manage high-voltage/current loads with minimal switching losses makes them indispensable in modern electrification and automation systems.

2. Main Types and Functional Classification

TypeFunctional CharacteristicsApplication Examples
Full-Bridge DriverControls four power transistors in H-bridge configuration, enabling bidirectional current flowBrushed DC motor control, servo actuators, resonant converters
Half-Bridge DriverDrives high-side and low-side transistors in complementary modeDC-DC converters, BLDC motor drives, Class-D amplifiers

3. Structure and Composition

Typical physical construction includes:

  • Multi-layer QFN/TSSOP packaging with thermal pad
  • Internal level shifters for high-side gate driving
  • Dead-time control logic to prevent shoot-through
  • Integrated protection circuits (OCP, OTP, UVLO)
  • Bootstrap circuitry for high-side power supply

Technical composition combines CMOS control logic with high-voltage DMOS output stages.

4. Key Technical Specifications

ParameterTypical RangeImportance
Operating Voltage4.5V-100VDetermines system compatibility
Peak Drive Current0.2A-4.0AAffects switching speed and efficiency
Switching Frequency100kHz-2MHzImpacts system size and EMI
RDS(on)50m -300m Directly affects conduction loss
Propagation Delay5ns-100nsCritical for high-frequency synchronization

5. Application Areas

  • Industrial automation (servo drives, robotic arms)
  • Electric vehicles (on-board chargers, DC-DC converters)
  • Consumer electronics (BLDC motor drives in appliances)
  • Medical equipment (precision actuator control)
  • Renewable energy systems (solar inverters, energy storage)

6. Leading Manufacturers and Products

ManufacturerProduct SeriesKey Features
TIDRV8703DThree-phase gate driver with current sensing
STMicroL6398High-voltage half-bridge driver with bootstrap
InfineonIRS2003300V half-bridge driver for Class-D audio
ON SemiNCP5911BSingle-channel high-side driver with diagnostics
RenesasISL78692Automotive full-bridge controller with PWM

7. Selection Guidelines

Key considerations:

  • Match voltage rating with system bus voltage (1.5x safety margin)
  • Calculate RMS current requirements vs. package thermal capability
  • Evaluate dead-time adjustability for specific switching frequency
  • Select appropriate protection features for operating environment
  • Consider package size vs. cooling requirements

Example: For 48V motor drives, select drivers with 80V rating, >1A peak current, and thermal shutdown.

Industry Trend Analysis

Future development focuses on:

  • Integration with current sensing and protection circuits
  • Adoption of wide-bandgap device drivers (SiC/GaN compatibility)
  • Intelligent drivers with digital interfaces (PWM/PWM with feedback)
  • Reduced on-resistance (<50m ) for high-current applications
  • AEC-Q100 automotive qualification becoming standard

The market is shifting towards higher integration and smarter power management solutions driven by EV and IoT applications.
