PT8A977B - 5 Function Remote Controller for 1V Micro Cars

General Description

The PT8A977B and PT8A9781 provide a complete control functions to the remote-controlled toy.

The PT8A9781 has four output pins corresponding with the four actions i.e, forward, backward, right, left.

The received signals are amplified by the three-stage amplifier, and then the appropriate amplified signals are sampled, fault-tolerantly checked and decoded to control the actions of the remote-controlled toy.
