GENERAL DESCRIPTION
A single external resistor is used to set the maximum LED current. Pulling the EN pin to GND disables the chip and reduces the supply current to less than 1uA. Additional features include a low-side NFET switch that can turn off the LED string with no DC current path to ground. Other features include OVP, OCP, UVP and OTP. The AME5136 is available in a small DFN-10( 3mmx3mmx0.85mm) package.
