MAX8855ETJ+T

MAX8855ETJ+T is Maxim Integrated’s Li‑ion/Li‑polymer battery charger and power‑path management IC for portable devices. It provides a complete charge‑management solution for a single-cell battery, combining a programmable constant‑current/constant‑voltage charging algorithm with system‑load power‑path control. Key features typically include:
- CC/CV charging with programmable charging current and termination
- Power‑path to feed the system while charging the battery
- Safety protections: overcurrent/short‑circuit, overvoltage, overtemperature, and undervoltage/UVLO
- Battery temperature sensing option (thermistor input) and status indicators for charging, complete, and fault
- Minimal external components, suitable for compact handheld designs
Packaging note: ETJ refers to the specific Maxim package, and +T indicates Tape‑and‑Reel shipping.
Common applications: smartphones, cameras, handheld instruments, USB‑powered accessories.
For exact electrical specifications, pinout, and typical application circuits, consult the MAX8855 datasheet.

MAX8855ETJ+T is a compact high‑efficiency buck regulator IC for portable power management. Key features include:
- Integrated high‑side switching buck regulator for easy single‑chip power conversion
- Wide input range suitable for Li‑ion/USB and battery systems
- Adjustable output via external feedback resistors (and fixed options in related parts)
- High efficiency with suitable operation in PWM/PFM modes
- Low quiescent current for long battery life and good light‑load efficiency
- Protections: overcurrent/short‑circuit, overvoltage, thermal shutdown, and UVLO
- Safe startup: soft‑start and current‑limit to minimize inrush and stress
- Enable/shutdown control and status/power‑good signaling
- Small package: ETJ+T, RoHS compliant, tape‑and‑reel format
Applications include portable devices, handheld electronics, and other battery‑powered systems requiring a compact, efficient regulator. For exact electrical specs and pinout, refer to the official MAX8855 datasheet.

"ETJ" is Maxim's package code and "+T" indicates tape-and-reel shipping. For the exact package style (pin count, footprint and mechanical dimensions), please consult the MAX8855 datasheet from the manufacturer.
