Power Management Integrated
Circuit (PMIC) for i.MX35/51
The MC13892 is a Power Management Integrated Circuit (PMIC)
designed specifically for use with the Freescale i.MX35 and i.MX51
families. It is also compatible with the i.MX27, i.MX31, and i.MX37
application processors targeting netbooks, ebooks, smart mobile
devices, smart phones, personal media players, and portable
navigation devices. This device is powered by SMARTMOS
technology.
Features
• Battery charger system for wall charging and USB charging
• 10-bit ADC for monitoring battery and other inputs, plus a coulomb
counter support module
• Four adjustable output buck regulators for direct supply of the
processor core and memory
• 12 adjustable output LDOs with internal and external pass devices
• Boost regulator for supplying RGB LEDs
• Serial backlight drivers for displays and keypad, plus RGB LED
drivers
• Power control logic with processor interface and event detection
• Real time clock and crystal oscillator circuitry, with coin cell backup
and support for external secure real time clock on a companion
system processor IC
• Touch screen interface
• SPI/I
