Before attaching the lithium battery pack, please insure
that jumpers OVP and V
the maximum pack voltage. Attach the battery pack to
the JBat connector by attaching the top of the pack
(positive) to the left most pin (looking into the connec-
tor) and the bottom of the pack (negative) to the right
most pin.
2.4
Rechargeable nickel based battery packs can be
attached to the PS2070. Before attaching battery cells,
please insure that jumpers OVP and V
configured for the maximum pack voltage. Attach the
battery pack to the JBat connector by attaching the top
of the pack (positive) to the left most pin (looking into
the connector) and the bottom of the pack (negative) to
the right most pin.

The Switch Mode Charger Evaluation Board includes a
simple buck topology charger using the PS200 IC. The
PS200 monitors the battery to determine its status. The
control is a dual loop design with hardware based
current feedback control and firmware based voltage
feedback control. The hardware is configured as a
constant current loop, controlling the Pulse-Width
Modulator (PWM). The firmware sets the current level by
adjusting the PWM signal at PS200 pin 5 (CTRL
The firmware also measures the voltage and dynami-
cally adjusts the current to maintain the fully charged
constant voltage value. Please refer to the “PS200 Data
Sheet” for details on configuring the PS200.
