Note 3: All devices are 100% production tested at T A = +25 ° C. Limits over the operating temperature range are guaranteed by
design.
Note 4: The input voltage range is specified with the external PFET off. When charging, the PFET turns on and the input voltage (the
output voltage of the constant-current power source) drops to very near the battery voltage. When the PFET is on, IN may be
as low as 2.5V.
Note 5: Every 20s (for CT = 0.33μF) the MAX1736 turns off the external P-channel MOSFET and samples IN to determine if input
power is present. If input power is removed, the charger shuts down.
Note 6: For design guidance, not tested.
