Pericom Semiconductor PT8A9701P
The PT8A9701P works as the encoder and the PT8A974P/974LP works as the decoder • Nine output pins, 5 for forward, backward, left, right and turbo functions, and 3 functional keys • Operation power supply for PT8A9701: 3V to 12V (with series resistor) • Auto power-off if no key pressed (PT8A9701P) • Motor current limit to meet toy safety standard HD271 (PT8A974P/974LP) • Low operating current • On-chip oscillator with an external resistor • On-chip reversing amplifiers • Built-in 3.7V Zener (Vz) (PT8A974P) and 3.1V Zener (Vz) (PT8A974LP) • Few external components needed General Description The... They have eight control keys for controlling the corresponding motion, i.e., forward, backward, left, right, turbo and 3 functional keys, of the remote controlled car. They also have ‘Forward (Backward)’ and ‘Turbo’ combination application.
