9.2.1.3 Application Curves

SETUP: BQ24040 typical applications schematic; V_IN = 5V, V_BAT = 3.6V (unless otherwise indicated)

Figure 9-2 Power-up Timing

Figure 9-4 – ASI and OUT Power-up Timing – No Input

Figure 9-6 OVP 8V Adaptor - Hot Plug

10kΩ resistor from TS to GND. 10kΩ is shorted to disable the IC

Figure 9-8 TS Enable and Disable

Figure 9-10 Battery Removal – GND Removed 1st, 42 Ω Load

Continuous battery detection when not in TTDM

Figure 9-12 Battery Removal with fixed TS = 0.5V

CH4: I_OUT (1A/Div)

Figure 9-14 ISET Shorted During Normal Operation

CH4: I_OUT (0.2A/Div)

Figure 9-16 DPM – Adaptor Current Limits – Vin Regulated

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

Figure 9-18 Thermal Reg. – Vin increases PWR/Iout Reduced

Figure 9-3 Power-up Timing – No Battery or Load

Figure 9-5 ASI and delayed OUT Power-up Timing – No Input

Figure 9-7 OVP from Normal Power-up Operation – V_IN 0V → 5V → 8V →5V

Fixed 10kΩ resistor, between TS and GND.

Figure 9-9 Hot Plug Source w/No Battery – Battery Detection
