Completed — BQ25157YFPR terminal organization
  • Updated all 20 physical balls into mutually exclusive groups:
    • Power: 9
    • Ground: 1
    • Digital: 3
    • Control: 4
    • Analog: 2
    • NC: 1
  • Set Section = Pin Group on every terminal.
  • Applied group-level terminal orders: 1, 3, 5, 7, 9, 10 as specified.
  • Applied orientations:
    • Power: Top
    • Ground: Bottom
    • Digital/Analog: Left
    • Control/NC: Right
  • Verified all 20 unique ball numbers from A1 through E4 are present exactly once.
  • Verified every terminal has Pin Group, Section, Terminal Order, and Pin Orientation.
  • Preserved pin numbers/names, pin types, symbol positions, footprint assets/mappings, and unrelated properties.
No blocked or uncertain items.Updated all 20 pins into broader groups: Power, Ground, Digital, Control, Analog, and NC. Section matches Pin Group on every pin; Power is order 1/Top, Ground is order 10/Bottom, and remaining groups alternate between Left and Right with no duplicated pins.

    Single-Cell Linear Li-Ion Battery Charger & Power Management IC – I²C-controlled single-cell lithium-ion/polymer battery charger with integrated power-path management, system voltage regulation, 16-bit ADC, and 150 mA LDO for wearables, IoT devices, medical electronics, wireless sensors, and portable embedded systems. Supports a programmable fast-charge current from 1.25 mA to 500 mA, operates from a 3.9 V to 6.05 V input, and provides a programmable battery regulation voltage from 3.6 V to 4.6 V in 10 mV steps. Features 10 nA ship mode, power-path management with regulated PMID output, integrated 150 mA low-dropout regulator (LDO), 16-bit ADC for monitoring battery voltage, charge current, input voltage, system voltage, and temperature, 6.2 V input overvoltage protection (OVP), JEITA-compliant temperature monitoring, watchdog timer, safety timers, NTC battery temperature sensing, and I²C programmable charging parameters. Specified for operation over a −40°C to +85°C temperature range and housed in a 20-ball DSBGA package.
