■General Description
The XC651A series are step-up DC/DC converter and multi voltage detector IC s.
CMOS processes and laser trimming technology provide high accuracy and low power
consumption.
The XC651A comprises of a PFM controlled step-up DC/DC converter, a voltage
detector with 4 x 5 level window comparators built-in, plus 2 other voltage detectors.
The step-up DC/DC converter's EN pin ( chip enable ) provides power consumption
savings when the step-up operations are not operating ( stand-by mode ).
The series is available in a small TSSOP-16 package.
■Features
Independent power supply for each built-in block :
Each of the following built-in blocks is operated by a separate power supply :
PFM controlled, step-up DC/DC converter ( PFM DC/DC )
5 level window comparator ( MWVD )
Negative Logic: XC651A3 Series
10
Positive Logic : XC651A4 Series
Voltage detector 1 with built-in delay circuit ( VD1 )
Voltage detector 2 ( VD2 )
Highly accurate set-up voltage :
PFM controlled, step-up DC/DC converter : set-up voltage accuracy 2.5ꢀ
5 level window comparator : set-up voltage accuracy 2ꢀ
Voltage detectors 1, 2 : set-up voltage accuracy 2ꢀ
Set-up voltage range :
PFM controlled, step-up DC/DC converter : 2.0V ~ 3.0V ( selectable in 0.1V steps)
5 level window comparator : 1.1V ~ 2.5V * ( selectable in 0.1V steps )
Voltage detectors 1, 2 : 0.9V ~ 3.0V ( selectable in 0.1V steps )
Operational voltage range :
0.9V ~ 6.0V
Small Package :
TSSOP-16
* Note :
The set-up voltage of the 5 level window comparator cannot be freely set-up due to the limitations of the circuit.
Please also note that the set-up voltage range of MWVD1 is 1.0V ~ 1.8V.
