Wireless remote control broadband decoding chip with drive function and application circuit thereof

Abstract

The invention discloses a wireless remote control broadband decoding chip with a drive function and an application circuit thereof. The wireless remote control broadband decoding chip integrates a broadband decoding unit, is low in requirement on frequency tolerance and allows frequency tolerance in a range of (-80%)-(+60%) is permitted, so that the chip is simple and convenient to produce and debug, and the production efficiency, the yield and the stability of the chip are improved; a motor driving unit is integrated, and the quantity of apparatuses of a peripheral circuit is reduced, so that the cost is lowered and the difficulty of production and debugging is lowered; an LDO unit is integrated, so that power ripple supplied to the chip and a radio frequency circuit is reduced, and the remote control distance of a remote control toy can be improved; a temperature protective unit is integrated, so that thermal damage of the chip can be effectively prevented, and the chip has good market promotional prospect.

Description

technical field [0001] The invention relates to the technical field of wireless remote control signals, in particular to a wireless remote control broadband decoding chip with a driving function and an application circuit thereof.
