PIN FUNCTIONS
The LTC3554/LTC3554-2 will partition the available power
between the external load on VOUT and the internal battery
charger. Priority is given to the external load and any extra
power is used to charge the battery. An ideal diode from
BAT to VOUT ensures that VOUT is powered even if the load
exceeds the allotted input current from VBUS or if the VBUS
power source is removed. VOUT should be bypassed with
a low impedance multilayer ceramic capacitor.
SUSP (Pin 19): Suspend Mode Logic Input. If this pin
is driven high the input current limit path is disabled.
In this state the circuit draws negligible power from the
VBUS pin. Any load at the VOUT pin is provided by the
battery through the internal ideal diode. When this input
is grounded, the input current limit will be set to desired
value as determined by the state of the HPWR pin. This
pin has a conditional internal pull-down resistor when
power is applied to the VBUS pin.
VBUS (Pin 20): USB Input Voltage. VBUS will usually be
connected to the USB port of a computer or a DC output
wall adapter. VBUS should be bypassed with a low imped-
ance multilayer ceramic capacitor.
GND (Exposed Pad Pin 21): Ground. The exposed package
pad is ground and must be soldered to the PC board for
proper functionality and for maximum heat transfer.
