Analog Devices ADuC7033 Integrated Precision Battery Sensor Anomaly List

About this manual

The document serves as an anomaly list for the ADuC7033 chip, detailing specific issues found in silicon revisions 8L/88 (A60) and BSTZ-88. It covers functionality issues such as LIN communication resets at high voltages, power-on reset failures under specific ramp conditions, and ADC overrange behavior.

Additionally, the text addresses performance issues including reduced ESD ratings for certain silicon batches and a latch-up failure on the WU pin that fails AECQ100 specifications. The document provides recommended workarounds or containment measures where available.

Frequently asked questions

What is the workaround for LIN communication resetting when VDD exceeds 31V?

The document states that a workaround is pending.

How can users prevent the Power-On Reset (POR) issue from occurring?

Analog Devices recommends ensuring the VDD supply ramp rate is guaranteed to be greater than 100 us under all conditions.

What is the recommended workaround for the WU pin latch-up issue?

It is recommended to use a protection diode, such as a BAS52, on the WU pin.
