TI drives high-voltage
batteries with industry’s first
100-V high-side FET driver
Unprecedented flexibility and power
protection for advanced industrial
battery applications
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
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.
Key features and benefits of the
bq76200: chip-01
Versatile supply voltage range:
Compatible with a variety of battery
architectures, capacities and voltage
ranges from 8-V 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 by 4.4-mm
by 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 TI’s CSD19531Q5A 100-
V NexFET™ power MOSFET as
showcased in the bq76200 evaluation
module.
Pricing and availability
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.
