DESCRIPTION Pin N° 1 2 3 4 5 6 7 Symbol GND SW GND SW Virtual GND LBO VREF IN Linear OUT LB Name and Function Switching Ground. Must be low impedance; solder directly to GND plane Switching Ground. Must be low impedance; solder directly to GND plane Virtual GND. Open Drain N-Cnannel MOSFET: must be high impedance when the Low Battery condition is detected. Low Battery Output. Open Drain N-Cnannel MOSFET: sinks current when the input voltage drops below 2V typically. Reference Voltage Output. Bypass with 0.1 µF to improve the linears VREF thermal noise performance. Linear Input. Must be connected togheter with IN SW to the input supply. Linear B Output port. 1.9V typically. 9 10 11 12 13 14 SHDN GND Signal OUT LA OUT DC/DC IN SW LX LX Shutdown Input. Disables the SMPS and LA output, but the LB, the referencevoltage and the low batery parator remain active. Signal GND. Must be connected togheter with the Switching Ground. Linear A Output port. 3V typically. DC/DC Output Port: 3.3V typically. SMPS Input. Must be connected togheter with IN_Linear to the input supply. 1.5A N-Channel Power MOSFET Drain. 1.5A N-Channel Power MOSFET Drain. 3/11 ELECTRICAL CHARACTERISTICS (Unless otherwise specified, please refer to the typical operating circut of the pag 1 for the external ponents values and connections. Unless otherwise noted VSHDN=HIGH) Symbol VI VO(DC/DC) Parameter Operating Input Voltage DC/DC Converter Output Voltage (Test Circuit A) 2.24<VIN<3.3V; 0<IO(LA)<20m A; -40 < TJ < 85 °C 0<IO(DC/DC)<200m A;...
