REVISION

Revised “VDDSMB Supply” on page 11 from:
“The VDDSMB input provides power to the SMBus interface. Connect VDDSMB to VCC, or apply an external
supply to VDDSMB to keep the SMBus interface active while the supply to DCIN is removed. When VDDSMB is
biased the internal registers are maintained. Bypass VDDSMB to GND with a 0.1µF or greater ceramic
capacitor.”
to:
“The VDDSMB input provides power to the SMBus interface. Connect VDDSMB to VCC, or apply an external
supply to VDDSMB. Bypass VDDSMB to GND with a 0.1µF or greater ceramic capacitor.
The typical application connects VDDSMB to the same power source as the SMBus master. This supply should
be active and greater than 2.5V when either the adapter or the battery is present.
ISL88731C does not function when VDDSMB is below its specified Under Voltage Lockout (UVLO) voltage. All of
the SMBus registers in ISL88731C are powered by VDDSMB and are set to zero when it is below the UVLO
threshold. Other functions are unpredictable when VDDSMB is below the UVLO threshold.”
VDDSMB UVLO Hysteresis limits updated to reflect actual test results
From (100, 150, 200 mV) to (40, 100, 150mV)
Added to Pin 3 VREF Pin Description on page 3 “It is internally compensated. Do not connect a decoupling
capacitor.”
-Converted to New Intersil Template
-Updated Related Literature's Application Note's Title to match application note
-Changed copyright to legal's suggested verbiage
-On page 2, Figure 3, Functional Block Diagram, ACOK comparator input changed from REF to 3.2V. "REF" was
a typo.
-Added Eval board to ordering information
-ACOK Leakage Current Test condition in Electrical Spec Table on page 7 changed from
ACIN = 2.5V to 3.7V. 3.7V has always been the test condition on this part.
-Removed Note: Limits established by characterization and are not production tested (no longer an Intersil
standard) and all references to it in switching regulators UGate and Lgate
-Changed Note:
Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature
limits established by characterization and are not production tested.
to new standard note:
Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or
design.
Added “Overvoltage Protection” on page 12 and Figure 17“OVERVOLTAGE PROTECTION IN ISL88731C” to
page 12.
