The MC13892EJVK from NXP Semiconductors is an 18-Channel Power Management IC that is ideal for ebooks, smart mobile devices, smartphones, personal media players, and portable navigation device applications. It has been designed specifically for use with NXPs i.MX35 and i.MX51 processor families and is also compatible with the i.MX27, i.MX31, and i.MX37 application processors. This 18-channel PMIC requires a DC supply of 2.8 - 4.65 V for operation. It consists of a battery charging system that includes a USB charging and a wall charging feature. This PMIC supports 10-bit ADC for monitoring the battery and other inputs.
This RoHS-compliant PMIC has four adjustable output buck regulators for direct supply of the processor core and memory, 12 adjustable output LDOs with internal and external pass devices, a boost regulator for supplying the RGB LEDs, and serial backlight drivers for displays and keypad, and RGB LED drivers. It also integrates real-time clock and crystal oscillator circuitry, with coin cell backup. This PIMC supports a touchscreen interface that can be controlled by SPI and I2C communication protocols. It is available in a surface-mount package that measures 7 x 7 x 0.92 mm.
