CHANDLER, Ariz., Sept. 27, 2016 /PRNewswire/ -- A new
Digitally Enhanced Power Analog (DEPA) controller designed to
regulate current, regulate voltage, and monitor temperature is now
available from Microchip Technology Inc. (NASDAQ: MCHP), a leading
provider of microcontroller, mixed-signal, analog and Flash-IP
solutions. The device improves digital support for battery charging
and is ideal for DC-DC conversion in server, consumer, industrial
and automotive applications.
The MCP19124/5 handles configurable charging algorithms
for any chemistry, with capabilities for cell balancing and super
capacitor charging. No other single-chip battery charging solution
can be configured with any desired charging profile, for any
battery chemistry, voltage or cell arrangement. Users may develop
their own unique charging methods and implement them as well. Any
voltage, current, temperature or duration can be used to trigger a
transition to a new portion of the charge profile. These devices
are also well suited for any DC-DC application requiring tight
voltage or current regulation; capable of supporting flyback,
boost, SEPIC, or Cuk topologies.
Benefits of the MCP19124/5 include:
- A unique combination of independent voltage and current control
loops. Either the current control loop can regulate to a
specified target current, or the voltage control loop can regulate
to a target voltage. Each analog control loop has a separate
feedback network for independent pole-zero placement and the
ability to perform zero cross detection for quasi-resonant
operation.
- The ability to dynamically switch from a voltage target to a
current target, or vice-versa, by switching between the two control
loops. The internal architecture ensures this transition is
monotonic, without glitching or transient events. This control
configuration even allows for pre-positioning of the output voltage
at open or no load conditions, greatly minimizing transients when a
load is applied.
- A full suite of configurable, adjustable performance
parameters. These parameters are set in the internal registers of
the device (no external components required), and the settings are
dynamically adjustable during operation.
- Integrated linear regulator, MOSFET drivers, 8-bit
PIC® microcontroller core, analog-to-digital converter,
precision oscillator and analog control loops for a compact
solution.
"Smarter, more capable battery charging solutions have become
vitally important for our customers," said Keith Pazul, director of marketing for
Microchip's Analog, Power, and Interface Division. "Customers have
been asking for the ability to run their own proprietary battery
charging profiles in compact, customizable charge circuits, and now
they can. This is the most flexible, most capable single-chip
charging solution on the market today."
