Part Number: BQ41Z90
Hello,
We are a bit confused about how the Wake pin should be handled when using SHUTDOWN or SHELF mode.
Based on Section 7.3.1.2.2.4 Wake Functionality, it appears that the Wake pin has an internal 5 V pull‑up and therefore does not require any external pull‑ups:
“A ≈5 V voltage is provided at the RADC4_Wakep pin with high source impedance.”
However, Section 7.3.1.2.2.3 SHELF Mode states that:
“Prior to entering the SHUTDOWN or SHELF mode, the Wake pin needs to pull up high to be able to wake up the device from shutdown.”
This makes us wonder whether an external pull‑up is required to ensure the device can wake from shutdown.
Could you please clarify whether the Wake pin needs any external pull‑ups?
Thank you!
