PRODUCTION DATA.
SETUP: bq21040 typical applications schematic; VIN = 5V, VBAT = 3.6V (unless otherwise indicated)
10-kΩ resistor from TS to GND. 10 kΩ is shorted to disable the IC |
Continuous battery detection when not in TTDM | ||
CH4: IOUT (1A/Div) |
CH4: IOUT (0.2A/Div) | ||
The IC temperature rises to 125°C and enters thermal regulation. Charge current is reduced to regulate the IC at 125°C. VIN is reduced, the IC temperature drops, the charge current returns to the programmed value |
CH4: IOUT (1A/Div) | ||
Battery voltage swept from 0V to 4.25V to 3.9V. |
CH4: IOUT (0.2A/Div) |
VIN swept from 5 V to 3.9 V to 5 V | VBAT = 4 V | |
