Description

The AM1139S is combination of two-channel H-Bridge driver for DC motor and RX receiver IC.   The AM1139S integrates the Motor and Logic supply Pins and a built-in Low Dropout Regulator (LDO).The AM1139S provides a high integrated motor-driver solution for R/C Car applications with the internal LED flashing signal output units. The output driver block consists of N-channel and P-channel power MOSFETs configured as two H-bridge to drive motor winding.
The AM1139S operates on two motor and a device power-supply voltage from 2.7 V to 6.8 V. CH_L/R can supply up to 0.8A of output continuous current and 2.0 A of output maximum current ; CH_F/B can supply up to 1.3A of output continuous current and 2.5 A of output maximum current. The AM1139S supports an internal shutdown function for Over-temperature protection (TSDp = 130℃ ) , Over-temperature protection recover (TSDr = 90℃ ) and a built-in Low Dropout Regulator(LDO).
Its package material is Pb-Free for the purpose of environmental protection and for the sustainable development of the Earth.
 
  • Applications: R/C Car
