MAX1551 Datasheet Sot23 Dual-input Usb/ac Adapter 1-cell Li+ Battery Chargers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX1551/MAX1555 SOT23 Dual-Input USB/AC Adapter 1-Cell Li+ Battery Chargers AVAILAB LE.

General Description

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 thermal limits imposed by worst-case battery and input voltage.

Key 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-blocking diodes are required to prevent battery drain. The MAX1551/MAX1555 are available in 5-pin thin SOT23 packages and operate over a -40°C to +85°C range.
  • Charge from USB or AC Adapter Fe.
