MAX8903A–E/G/H/J/N/Y
2A 1-Cell Li+ DC-DC Chargers
for USB and Adapter Power
ELECTRICAL CHARACTERISTICS (continued)
(V DC = V USB = 5V, V BAT = 4V, circuit of Figure 2, T A = -40°C to +85°C, unless otherwise noted. Typical values are at T A = +25°C.)

Note 1: Limits are 100% production tested at T A = +25°C. Limits over the operating temperature range are guaranteed by design.
Note 2: For the 100mA USB mode using the DC input, the step-down regulator is turned off and its high-side switch operates as a
linear regulator with a 100mA current limit. The linear regulator’s output is connected to LX and its output current flows
through the inductor into CS and finally to SYS.
Note 3: For the 500mA USB mode, the actual current drawn from USB is less than the output current due to the input/output current
ratio of the DC-DC converter.
Note 4: For short-circuit protection, SYS sources 25mA below V SYS = 400mV, and 50mA for V SYS between 400mV and 2V.
