BQ25170: Battery Charger Schematic and PCB Layout Review

Part Number: BQ25170

Tool/software:

Hello,

I'd like a review of my PCB layout for integrating the BQ25170 as my battery charger. The PCB is a small 18.6mm in diameter circle for a wearable device.

I'd like to see if there are any issues with my component placement and traces.

PCB is 4 layer with 3 layer GND and bottom layer 1.8V.

I'm using a thermistor on TS for temperature monitoring.

Battery charge voltage is 4.2V at 100mA.

Thank you!
