A51DC More Information

D/C: 92+


If a foreign object contacts a key the signal may change enough to create a 'false' detection lasting for the duration of the contact. To overcome this, the IC includes a timer which monitors detection duration. If a detection exceeds the timer setting, the timer causes the sensor to perform a full recalibration. This is known as the Max On-Duration feature.

The Hynix HYM71V16M635B(L)T8 Series are 16Mx64bits Synchronous DRAM Modules. The modules are composed of eight 16Mx8bits CMOS Synchronous DRAMs in 400mil 54pin TSOP-II package, one 2Kbit EEPROM in 8pin TSSOP package on a 144pin glass-epoxy printed circuit board. One 0.22uF and one 0.0022uF decoupling capacitors per each SDRAM are mounted on the PCB.


  During internal PWM operation, at the end of the tOFF time, the comparators output is blanked and CT begins to be charged from approximately 1.1 volts by an internal current source of approximately 1 mA. The comparator output remains blanked until the voltage on CT reaches approximately 3.0 volts.
