SY6970 Power Management Interface

This class provides control over power management functions including:

• System minimum voltage
• Input voltage/current limits (VINDPM)
• OTG (On-The-Go) boost mode
• Boost output voltage

Management Features

• VINDPM (Voltage Input Dynamic Power Management): Protects input source by limiting power draw based on adapter capability
• AICL (Auto Input Current Limit): Automatically adjusts input current based on detected adapter limits
• OTG/Boost Mode: Converts battery power to VBUS for powering USB devices

Parameters

• System minimum: 3000-3700mV (100mV steps)
• Input voltage limit (VINDPM): 3900-15300mV (100mV steps)
• Input current limit: 100-3250mA (50mA steps)
• Boost voltage: 4550-5510mV (64mV steps)

Note

All setter methods with step requirements will automatically quantize input values to the nearest valid step if they do not match exactly.
