MCP19124/5 contains independent voltage and current control loops; plus a full suite of configurable performance parameters
A new digitally enhanced power analog (DEPA) controller designed to regulate current, regulate voltage, and monitor temperature is now available from Microchip Technology. The device improves digital support for battery charging and is ideal for DC-DC conversion in server, consumer, industrial and automotive applications.
As per the release, 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, the ability to dynamically switch from a voltage target to a current target, or vice-versa, by switching between the two control loops, a full suite of configurable, adjustable performance parameters and integrated linear regulator, MOSFET drivers, 8-bit PIC microcontroller core, analog to digital converter, precision oscillator, and analog control loops for a compact solution.
Keith Pazul, director of marketing for Microchip’s Analog, Power, and Interface Division said, “Smarter, more capable battery charging solutions have become vitally important for our customers. Customers have been asking for the ability to run their own proprietary battery charging profiles in compact, customisable charge circuits; and now they can. This is the most flexible, most capable single chip charging solution on the market today.”
