ELECTRICAL CHARACTERISTICS - ALL OPERATIONAL MODES
Note:
6. No external loads should be connected to the LFILT+ net. Any connection of a load to this point may
result in errant operation or performance degradation in the device.
7. When VBATT is below this threshold (VBLIM), operation is automatically restricted to SD mode.
8. When operating in HD or FHD mode and the differential input voltage remains below the input level
threshold (VIN-LDO) for a period of time (tLDO), the PWM outputs will be powered by the internally
generated LDO supply (VLDO).
9. When operating in HD or FHD mode and the differential input voltage is above this input level
threshold (VIN-VBATT), the PWM outputs will be powered directly from the VBATT supply.
10. Refer to Section 5.5 for more information on Thermal Error functionality.
11. Under Voltage Lockout is the threshold at which a decreasing VBATT supply will disable device
operation.
