BQ40Z60: Driving LED with TSx IO

Part Number: BQ40Z60

I have a custom board with BQ40Z60.

I am trying to drive an LED with TS1 and have the LED blink whenever the battery is charging. I want the LED off when the battery is not charging. The LEDCHG bit is set.

Problem:

Whenever the battery is charging, I get the wanted outcome - the LED connected to TS1 blinks. However, when the battery is not charging (both when charger is unplugged or RSOC is 100%), LED driven by TS1 is solidly on. I saw that the evaluation kit had a 10k thermistor that acted as a pulldown. So, I added in a 10k to ground to pull down the TS1 pin. This turned off the LED but the blinking no longer works when charging.

What exactly is going on and how can I fix thisAttached is the srec and the schematic.

Thank you,

Juwan
