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.
Features
