Other Parts Discussed in Thread: TPS2116, TPS2117
Tool/software:
I followed the application example in the datasheet and am still having an issue. I have two inputs: USB (5v) and LiPo (<4.1v). The usb feeds a battery charging IC.
The Batt+ is IN1 and the USB is IN2.ILIM is pulled to ground via 400 ohm resistor.
D1 is grounded. D0 is held high (I have also connected it to ground when it didn't work). The truth table says that with D1 LOW, D0 HIGH, and ILIM<.8v; the output should select the greater of V1 and V2 (desired).
The TPS correctly selects the USB when it is attached but outputs 0v when USB is detached. I would expect it to output Batt+ (3.4-4.1v). Any advice is welcomed.
