Hello,
TPS1HB50-Q1's data sheet defines some VBB voltage specs, but I'm wondering how to understand some of them.
Data Sheet Specs
- Absolute Maximum Ratings
- Maximum continuous supply voltage, VBB: 36 V (Max)
- Recommended Operating Conditions
- VBB – Nominal supply voltage: 6 to 18 V
- VBB – Extended lower supply voltage: 3 to 6 V
- VBB – Extended higher supply voltage: 18 to 28 V
- Electrical Characteristics
- VBBCLAMP – VBB clamp voltage: 58 to 76 V
Questions
- What are the "extended lower supply voltage" and "extended higher supply voltage" specs? I'm not sure what are the differences from the "nominal supply voltage" specs.
- I guess a VBB voltage is clamped when a voltage applied to the VBB pin exceeds the VBB clamp voltage, but could the voltage damage the device? The VBBCLAMP specs are higher than the absolute Max VBB voltage.
Best regards,
Shinichi Yokota
