FUNCTION
Connection to Battery. Connect to a single-cell Li+/Li-Poly battery from BAT to PGND. Connect both
BAT pins together externally. Bypass BAT to PGND with a 2.2 F F ceramic capacitor.
40m I Current-Sense Node. Connect the inductor from LX to CS. Connect both CS pins together
externally.
Inductor Switching Node. Connect the inductor between LX and CS. Connect both LX pins together
externally. When enabled ( CEN = 0), LX switches between INBP and PGND to control the battery
charging. When disabled ( CEN = 1), the LX switches are high-impedance however they still have
body diodes as shown in Figure 3.
Power Ground for Step-Down Low-Side Synchronous n-Channel MOSFET. Connect all PGND pins
together externally.
Supply for High-Side n-Channel Gate Driver. Bypass BST to LX with a 0.1 F F ceramic capacitor.
5V Linear Regulator to Power Internal Circuits. PVL also charges the BST capacitor. Bypass PVL to
PGND with a 1.0 F F ceramic capacitor. Powering external loads from PVL is not recommended.
Status Output 2. STAT2 is an open-drain output that has a 30V absolute maximum rating and a typical
pulldown resistance of 25 I . For the MAX8900A, STAT1 and STAT2 indicate different states as shown
in Table 4. For the MAX8900B/MAX8900C, STAT1, STAT2, and STAT3 indicate different operating
states of the MAX8900_ as shown in Table 3.
Charge Enable Input. CEN has an internal 200k I pulldown resistor. Pull CEN low or leave it
unconnected to enable the MAX8900_. Drive CEN high to disable the MAX8900_. Note: V IN must be
greater than V UVLO-RISING for the MAX8900_ to operate when CEN is pulled low. For example, if CEN
is low and the MAX8900_ is operating with V UVLO-FALLING < V IN < V UVLO-RISING , then toggling CEN
results in a nonoperating condition.
