WTD0007

WTD0007 is a chip dedicates to detect the heart-rate signal from human body.Only a few extemal components need, WTD0007 can implement functions via connecting to three kinds of heart rate detecting sensor.Support IR photo-interrupt,photo-transmit and electrode metal sensors(hand pulse sensors),WTD0007 is adapted to various products such as exciting instruments,bicycle and heart rate watch.

WTD0007 has the following features: micro processor base; standby current less  then 1 A; heart-rate signal detect circuit build in; 16 bit sampling heart rate signal to digital counter; auto wake up via simple trigger; supply voltage 2.4V~3.6V for IR photo sensor; supply voltage 2.5V~4.5 for hand pulse sensor;hand-holding detect function;20 pin SSOP package or die.
