YT5166 Datasheet Text
PRODUCT SPECIFICATION V 2.0 Ref: QB-PT003
DESCRIPTION
The YT5166 is a semiconductor integrated circuit for use in servo motor in radio control applications. The built-in voltage regulating circuit, and the differential parator used in the parator circuit provide the YT5166 with extremely stable power supply voltage fluctuation characteristics and temperature change characteristics.

FUNCTION
When a peripheral PNP transistor is connected to YT5166, a direct current pulse-duration modulation circuit is pleted. When the control input PIN2 (IN) input an adjustable pulse of 20ms cycle and 1.0-2.0ms pulse-duration, the bridge PWM circuit will input accordingly a forward-backward

PIN CONFIGURATION approximately 2.6v and the average voltage on load will be zero. When output pulse duration is increased (decreased), one side (or the other side) of the bridge circuit is turned on. The period of turning on is the direct ratio with the difference between input pulse-duration and balance point (1.5ms). When pulse-duration is 2.0ms, load voltage is close to +Vcc. When pulse-duration is 1.0ms, load voltage is close to -Vcc. When input pulse-duration is balance (1.5ms) and output is not balance, adjust voltage of PIN11 to balance. With this characteristic, the bridge circuit...
