Texas Instruments (TI) (NASDAQ: TXN) today introduced the first single-chip 100-V high-side FET driver for high-power lithium-ion battery applications, delivering advanced power protection and control. The bq76200 high-voltage solution efficiently drives high-side N-channel charge and discharge FETs in batteries commonly used in energy storage systems and motor-driven applications, including drones, power tools, e-bikes and more. For more details, see http://www.ti.com/bq76200-pr.
Compared to typical 50-V low-side FET driver solutions, the 100-V high-side FET driver provides greater protection against possible inductive transient events in motor-driven applications, which can cause battery voltages to jump as much as 200 percent above normal. The bq76200 also helps maintain constant battery monitoring and enhanced system diagnostics – even when charging and discharging is disabled.
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 TI’s CSD19531Q5A 100-V NexFET™ power MOSFET as showcased in the bq76200 evaluation module.
The bq76200 is available now in the TI store and through the company’s authorized distribution network. The driver is packaged in a 16-pin TSSOP and is priced at US$1.69 in 1,000-unit quantities.
