Improve Digital Support of Battery Charging and DC-DC Conversion Applications with New Digitally Enhanced Power Analog Controllers from Microchip



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

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.

Key Features of the MCP19124/5:

  • Smooth, dynamic transitions from constant-current to constant-voltage operation using the unique control loop architecture
  • Dynamically adjustable output current and output voltage over a wide operating range
  • Wide operating voltage range: 4.5-42V
  • Analog peak-current mode Pulse-Width Modulation (PWM) control
  • Integrated 8-Bit PIC┬« Microcontroller
  • Significant configurability: adjustable output voltage, output current, MOSFET deadtime, leading edge blanking time, thermal responses, slope compensation, over-current protection, over and under voltage lockout levels
  • Available fixed frequency or quasi-resonant operation, adjustable 31 kHz to 2 MHz
  • I2C communication interface
  • 13 GPIO
  • Integrated synchronous low-side MOSFET drivers
  • Integrated high voltage linear regulator, with external output
  • Integrated temperatures sense diode
  • Integrated 10 bit A/D converter
  • Minimal external components needed
  • Custom algorithm support
  • Topologies supported include Boost, SEPIC, Flyback, and Cuk
