I cannot identify pin 1 on the TLV3011 SOT-23-6 device with 100% certainty.
My prototype simple battery over-voltage protection circuit with hysteresis using the tlv3011 simply refuses to work. Maybe I have misidentified pin 1 on the package.
The data sheet shows a chamfered area at the corner of the package rectangle that identifies pin 1. However, the delivered device has no such chamfering. Printed on top of the device is "ALR". I chose pin 1 as being near the first leg of the "A". MAYBE there is a small divit in the opposite corner to identify pin 1. Maybe my loupe is not strong enough. Should there be a divit and I just can not see it?
Pin behavior behaves SOMEWHAT correctly (default position Vref pin is at 1.248) volts, but still, the simple circuit (based on the data sheet "Battery Good" circuit) absolutely refuses to operate correctly. I am very confused.
Silly, I know. But can someone please help me find this. The next step, if I was correct in finding pin 1, is to post the circuit and ask for help.
Thank you, in advance.
