PACKAGE/ORDER INFORMATION

S6 PART MARKING

LTE6

The q denotes the specifications which apply over the full operating

temperature range, unless otherwise noted specifications are at TA = 25°C. VCC = 5V, GND = 0V and VBAT is equal to the float voltage

unless otherwise noted. All current into a pin is positive and current out of a pin is negative. All voltages are referenced to GND,

unless otherwise specified.
