IXYS Announces Digitally Controlled Surge Voltage, Inrush, and Short-Circuit Protection Design for Battery Powered Devices
March 28 2017 - 8:30AM
IXYS Corporation (NASDAQ:IXYS), a global manufacturer of power
semiconductors and ICs for energy efficiency, power management,
transportation, medical, and motor control applications, today
announced a digital power design that demonstrates surge voltage
protection as well as inrush current and short-circuit protection
for battery powered devices based on the Zilog MCU.
This reference design demonstrates the cost
effective use of proven Zilog MCU for digital power control,
integrating IXYS power and digital control software in one ready to
use design.
Compared to hardware only solutions, digital
control ones help simplify the system and provide power designers
with a greater flexibility at the same time. This design makes use
of the Z8F3281 microcontroller (MCU) from Zilog, Inc. for digital
control. It protects the load from transient voltage spikes
emanating from the battery and also safeguards the battery from
inrush current and short-circuit conditions at the load.
The load current can range from 0 to 20A, and
the output voltage is programmable from 12V to 48V, using the MCU
or an external resistor divider. The inrush current limit is set at
30A, and the surge voltage protection is up to 150V. At a load
current of 20A, the efficiency is at 99 percent in the idle state.
When the output voltage is at 24V, it becomes 99.5 and 98 percent
at 48V and 12V, respectively.
The design consists of a power component board
(3.6 x 2.6 x 1.6 inches) and microcontroller module (1.3 x 1 x 0.5
inches). The schematics and bills of material are also
available.
