One Device Replaces Battery Charger, Pushbutton Controller,
LED Driver and Voltage Regulator ICs in Portable Electronics
Design Note 470
Marty Merchant
Introduction
The LTCВ®3577/LTC3577-1 integrates a number of portable
device power management functions into one IC, reducing
complexity, cost and board area in handheld devices. The
major functions include: Five voltage regulators to power memory, I/O, PLL,
CODEC, DSP or a touch-screen controller A battery charger and PowerPathв„ў manager An LED driver for backlighting an LCD display, keypad
and/or buttons Pushbutton control for debouncing the on/off button,
supply sequencing and allowing end-users to force a
hard reset when the microcontroller is not responding
By combining these functions, the LTC3577/LTC3577-1
does more than just reduce the number of required ICs; it
solves the problems of functional interoperabilityвЂ”where
otherwise separate features operate together for improved
end-product performance. For instance, when the power
input is from USB, the limited input current is logically
distributed among the power supply outputs and the
battery charger. Status output indicates when the pushbutton is depressed,
allowing the microprocessor to alter operation or begin
the power-down sequence. Holding the pushbutton down …
