Function
CHG MON
Constant-current feedback input
pin for the charging circuit. The
charging current is determined
by comparing this input voltage
and the internal reference
voltage (0.35 V typ.).
Connection pin for the resistor
that is used to set the voltage for
the external step-down circuit.
This prevents invalid current at
no power supply.
LB8118M GND pin for
small-signal block. (GND except
output power Tr)
Input pin for the free-running
oscillation circuit that is used to
operate the PWM step-down
circuit and step-up circuit. The
oscillating frequency is
determined by external
capacitors.

EXT
Voltage feedback input pin for
the external power supply
step-down circuit. V
CC
for
playback is set by comparing
this pin voltage with the internal
reference voltage (1.28 V typ.).

EXTCHG
Voltage feedback input pin for
the external power supply
step-down circuit. V
CC
for
charging is set by comparing this
pin voltage with the internal
reference voltage (1.28 V typ.).

V
ASP
Voltage feedback input pin for
the step-up circuit. The step-up
voltage is determined by
comparing this pin voltage with
the internal reference voltage
(1.28 V typ.).
19
UPBASE
Connection pin for the resistor
that is used to set the voltage of
the step-up circuit. This prevents
invalid current in standby mode.

startup circuit
External
Forced
Input pin for start-up circuit when
an external voltage input is
applied. The external voltage
input is applied through a
resistor inserted in series. The
voltage is basically determined
1.2V + 2V
BE
; this pin has a
current draining capacity up to
20 mA.
LB8118M start-up input. (Start
on a low-level input.)
