M4T28-BR12SH1 Battery: M4T28-BR12SH1 Datasheet, Logic Diagram

The M4T28-BR12SH1   SNAPHAT  top is a detachable lithium power source. The SNAPHAT  top contains both the battery and crystal and is designed to be snapped on after the SOIC  is surface mounted on the PC board. Thus the two-piece solution prevents the battery and crystal from being exposed to the high temperatures of the surface mount process.

 Provides battery backup power  for the serial real-time clock, non-volatile TIMEKEEPER  ® and supervisor devices in the 28 - or 44 -pin SNAPHAT® SOIC package
 Removable battery avoids heat associated with the surface-mount process
 Snaps directly onto surface-mounted SNAPHAT SOIC 
 Choice of battery capacities
– M4T28-BR12SH = 48  mAh
– M4T32-BR12SH  = 120  mAh
 Keyed insertion to ensure proper assembly
 Removable for replacement and proper disposal
 Pb-free package
 Available in Ecopack® packages, tubes

The figure shows below illustrates the lithium coin cell discharge rate for a given load. This demonstrates the characteristically flat voltage level supplied by the battery until very near the end of its life. These discharge levels have been greatly accelerated in comparison to the normal, actual usage.
