ISL9238 and ISL9238A add 5V-20V reverse boost for
USB On-The-Go charging of smartphones, headphones
and more
Intersil Corporation (NASDAQ: ISIL), a leading provider
of innovative power management and precision analog
solutions, today introduced two new USB-C™ buck-
boost battery chargers that support bidirectional power
delivery in ultrabooks, tablets, power banks and other
mobile products. The single-chip ISL9238 and ISL9238A
battery chargers replace competitive two-chip solutions
to reduce customer bill of materials (BOM) costs by
up to 40%. Both ICs employ Intersil’s patented R3™
modulation technology to extend battery life and deliver
acoustic noise-free operation, superior light-load
efficiency and ultra-fast transient response.
The ISL9238 and ISL9238A operate in forward buck,
boost or buck-boost mode to fast charge mobile battery
packs with up to 4-cell Li-ion batteries. They also
support USB 3.1 On-The-Go (OTG) with 5V/20V reverse
buck, boost or buck-boost mode to deliver power out
of a USB-C port for charging external devices such as
smartphones, headphones or virtual reality goggles.
At maximum power, both ICs provide 20V at 5A to the
USB-C port for delivery of power up to 100W over a
reversible USB Type-C connector cable. The ISL9238A
features the same capabilities as the ISL9238, but also
includes a different SMBus address for OEMs that want
to use both ICs to design systems with dual USB-C ports.
In charging mode, the ISL9238 and ISL9238A take input
power from a wide range of DC power sources, including
AC/DC charger adapters, USB power delivery (PD) ports
and any travel adapter. Both chargers include SMBus
and I2C programmable features such as depleted battery
trickle charging, and a two-level adapter current limit for
turbo-mode events where the charger takes advantage
of the adapter’s milliseconds of surge current capability
to minimize power draw and extend battery run-time.
The ISL9238 and ISL9238A also feature programmable
autonomous charging and an end of charge safety timer
to stop battery charging.
“The new ISL9238/A USB-C buck-boost battery
chargers give our customers more features, including
5V/20V reverse buck, boost and buck-boost modes,
and the ability to add dual ports for two USB-C battery
chargers in one system,” said Andrew Cowell, senior
vice president of Mobile Power Products at Intersil.
“Mobile computing OEMs rely on Intersil to consistently
deliver power management innovations that help them
differentiate their products with thinner form factors and
exceptionally long battery life.”
The ISL9238 and ISL9238A are pin-compatible with the
ISL9237 USB-C battery charger and join Intersil’s family
of mobile computing power management solutions,
including the ISL95852 Vcore PMIC, ISL95908
peripheral PMIC, and discrete PWM controllers
(ISL95853/54/55/57). These ICs power IMVP8-compliant
mobile systems using 6th and 7th Gen Intel® Core™
processors.
