MAX1555, MAX1551, SOT23 Dual-Input USB/AC Adapter 1-Cell Li+ Battery Chargers
The MAX1551/MAX1555 charge a single-cell lithium-ion (Li+) battery from both USB and AC adapter sources.
They operate with no external FETs or diodes, and accept operating input voltages up to 7V.
On-chip thermal limiting simplifies PC board layout and allows optimum charging rate without the therma
MAX1555 Features
* a CHG output to indicate charging status. With USB connected, but without DC power, charge current is set to 100mA (max). This allows charging from both powered and unpowered USB hubs with no port communication required. When DC power is connected, charging current is set at 280mA (typ). No input-bl
