AC OPERATING CHARACTERISTICS TA= -30°C to +85°C, VIN = +5.0V, VFLOAT = +4.2V unless otherwise noted. All voltages are relative to GND. Symbol Description Conditions Min Typ Max Unit Oscillator fOSC Frequency range 250kHz steps (3 settings) 750 1250 kHz ∆fOSC Frequency accuracy fOSC=1.25MHz (default), T=0 oC to +70 oC 1.125 1.250 1.375 MHz tSTART Start-up time Note 5 20 ms Disabled 0 msec tGLITCH Glitch filter Enabled 250 msec Short 0 1 msec tHOLDOFF Hold-off time Long 256 msec tFCTO = 350min tFCTO = 699min tFCTO Fast-charge Timeout tFCTO = 1398min -15 tFCTO +15 % tPCTO = 44min tPCTO = 87min tPCTO Pre-charge Timeout tPCTO = 175min -15 tPCTO +15 % Note 5: This is the time it takes for the device to be ready for I2C communication or charging after power-up (including coming out of shutdown). When charging is enabled, actual charging begins after the hold-off timer has expired. |
