TSB41BA3 not releasing reset

Other Parts Discussed in Thread: TSB41BA3A-EP

before i shotgun the chip i was wondering what could possibly be keeping the reset line low (spec says if PD is high an internal pull-down will keep reset low) but PD is pulled to GND. this is a proven design in production for 10 years.

Hello,
It could be a damaged chip, is it always low or does it get stuck in low after you de-assert PD?

It is always low and PD is directly connected to GND through a 0Ω resistor. For reference the specific chip we use is the TSB41BA3A-EP and the thermal pad is not soldered (we are in the process of changing the build instructions to attach the thermal pad).
