• Manufacturer Part Number: bcm59001
• Description: Bcm59001 - Mobile Power Management Unit
• Manufacturer: Broadcom Corp.

The BCM59001 is a highly integrated and complete power management
solution specifically designed for midrange Li-Ion- or Li-Pol-powered
mobile handhelds.
Power Management
This device implements advanced power management including two
highly efficient switching regulators for core and I/O supply and 11 high-
performance LDOs with ECO mode. The peak efficiencies of the
switching regulators are 93% and ~83% at 1 mA low-power mode.
A switching frequency of 2 MHz enables small 2.2-μH inductors and
4.7-μF output capacitors. The output voltage of the switching regulators
and the LDOs is I
Battery Management
The battery management system has a wide input voltage range of up to
20V to enable operation with inexpensive chargers. It features a CC/CV
USB/wall adapter linear charger with automatic charging source
detection and a CC/CV mode backup battery charger. This system has
extensive protection, monitoring, and safety features such as charger

overvoltage and overcurrent protection on the wall adapter pin and
watchdog timer circuit. In addition, the device features accurate USB
current limiting, and the highly accurate coulomb counter-based fuel
gauge provides precise measurement of the remaining battery voltage.
Controls and Interfaces
The BCM59001 has 100/400-kHz I
communication with the host controller for built-in state machine, on/off
control module, interrupt control and monitoring circuits. The aggressive
energy management is achieved through additional power control pin
interface which controls sleep cycle quiescent current states. PONKY,
accessory detection, and hands-free detection supports phone power on/
off remote key and headset detections with debounce. Two
programmable PWMLED current sources are available to drive vibrator
and/or LEDs. RTC provides time reference and alarm functions with
wake-up control. Chip features extensive protection and monitoring
including overvoltage, overcurrent on chargers and all regulators,
thermal shutdown, and 6-kV ESD on use-accessible pins.
