Part Number: TPS62742 Other Parts Discussed in Thread: BQ24091 Dear team,
Customer find tps62742 seems latch-up when going on ESD test. Please refer to attached schematic.
When customer begin ESD test (8Kv) on Vbus or GND of bq24091…
Part Number: BQ24092 Other Parts Discussed in Thread: BQ24090 , BQ24091 , BQ24095 , BQ24093 Does BQ24092 conform to the JEITA specification?
Does TI have a specification for JEITA?
What does JEITA design need to be aware of?
Part Number: BQ24090 Other Parts Discussed in Thread: BQ24091 I saw the op temperature of BQ24090 and BQ24091 is different in the datasheet.
But I can not find other explain about this difference.
An NTC value of 10k ohms should work for the BQ24090, BQ24092 and BQ24095. Package marking 24090, 24092 and 24095.
But the BQ24091 and BQ24093 will require an NTC value of 100k ohms. Package marking 24091 and 24093.
Have you checked the board to verify…
No, I cannot suggest a PMIC with NUC972 specific voltage/sequencing requirements and built-in battery charger.
Built in battery chargers in PMICs are not very common.
The TPS65023 is a hardware-configurable PMIC: the voltages are set by resistor dividers…
Other Parts Discussed in Thread: BQ24093 , BQ24092 , BQ24091 Hi,
I was looking for a NTC 100k B3370 (K factor). Unfortunatly, It seems that type of NTC is is not common value which make me to wonder about the K factor. The bq24092 is made for 10k NTC β =…
Other Parts Discussed in Thread: BQ24091 I want to test the BQ24091 evm and was wondering if there was a way to simulate charge/discharge characteristics ? For example, is there a tool on webench?
I know TI has the TINA software and I want to know if its…
