High-Side N-Channel FET Driver

Texas Instruments recently introduced the a single-chip, 100-V, high-side FET driver for high-power lithium-ion battery applications. Offering advanced power protection and control, the bq76200 high-voltage solution drives high-side N-channel charge and discharge FETs in batteries commonly used in energy storage systems and motor-driven applications (e.g., drones, power tools, e-bikes, and more). TexInst bq76200

Compared to 50-V low-side FET driver solutions, the 100-V high-side FET driver provides increased protection against possible inductive transient events in motor-driven applications. It also helps maintain constant battery monitoring and enhanced system diagnostics.

Key features and benefits:

  • Versatile supply voltage range: Compatible with a variety of battery architectures, capacities and voltage ranges from 8 to 75 V, with an absolute maximum of 100 V.
  • Advanced-protection FET control: The fast-switching feature minimizes fault response time and disables the discharge FET if a battery has been severely discharged.
  • Quick development time and reduced overhead: The adaptable driver works with small to large power FET arrays by simply scaling the charge-pump capacitor, reducing engineering overhead and speeding development time.
  • High integration and small package size: The bq76200 integrates a high-voltage charge pump and dual FET drivers into one 5 mm × 4.4 mm × 1 mm thin shrink small outline package (TSSOP).

The bq76200 can be used in conjunction with the bq76940 battery-monitoring family, allowing for the application to move to a high-side FET drive and ensure that communication is always possible. The bq76200 can also drive Texas Instrument’s CSD19531Q5A 100-V NexFET power MOSFET as in the bq76200 evaluation module.

The bq76200 is available now. The driver (six-pin TSSOP) costs $1.69 in 1,000-unit quantities.

Hands-On Test Instrument Workshop Tour

Keysight recently announced it is running hands-on, test instrument workshop for design and test engineers.The workshop series (February 2–June 24) will be held in the United States and Canada.

The workshop is intended to focus on top test challenges with seminars and instructors leading demonstrations and lectures. Attendees can use high-performance and general-purpose oscilloscopes, RF signal analyzers and sources, RF network analyzers, AC/DC power analyzers, and bench instrumentation.

Workshop highlights include:

  • Power Integrity and Analysis Using Oscilloscopes and Power Analyzers
  • RF Transmitter/Receiver Measurements
  • Faster and Simpler Design Validation/Characterization

In addition, attendees will receive a course completion certificate and will be entered into a drawing for a free U1273A 4.5 digit, OLED display hand-held digital multimeter with a U117A Bluetooth adapter.
