Low-ESR Surface-Mount Ceramic Capacitors 8MLCCs) used in setting electrical characteris- tics. LSB Least Significant Bit 30 mV EABS Total Unadjusted Error 5 VIN_TEST = 0V to VBAT <±3 ±4 LSB tCONV Conversion Time 2.7 ms VIN_TEST DC Voltage Range 0 5 V Logic Interface Logic Input EN VIL Input Low Level 0.5 V VIH Input High Level 1.2 V IIN Input Current -1.0 1.0 µA tDELAY Input Delay 6 2 µs Logic Input SCL, SDA, TRIG, CLK32K, ASEL0, ASEL1 VIL Input Low Level 0.2x VEN V VIH Input High Level 0.8x VEN V IIN Input Current -1.0 1.0 µA Logic Output SDA, TRIG, INT VOL Output Low Level IOUT = 3 mA (pull-up current) 0.3 0.5 V IL Output Leakage Current VCP = 2.8V 1.0 µA Logic Output GPO VOL Output Low Level IOUT = 3 mA 0.3 0.5 V VOH Output High Level IOUT = -2 mA VBAT - 0.5 VBAT - 0.3 V IL Output Leakage Current VCP = 2.8V 1.0 µA Logic Input CLK32K fCLK Clock Frequency 32.7 kHz fCLKH High Time 6 µs fCLKL Low Time 6 µs tR Clock Rise Time 10 to 90% 2 µs tF Clock Fall Time 90 to 10% 2 µs 1. In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature (TAmb-MAX) is dependent on the maximum operating junction temperature (TJ-MAX =125°C), the maximum power dissipation of the devi ce in the application (PD-MAX) and the junction to ambient thermal resistance of the part/package in the application ( θ JA) as given by the following equation: TAmb-MAX = TJ-MAX - ( θ JA * PD-MAX ). 2. Turn-on time is measured from the moment the charge pump is activated until the VCP crosses 90% of its target value Table 3.
