MAX4987AEETA+T Description

Short technical summary and product information.

The MAX4987AEETA+T is an overvoltage protection controller designed by Analog Devices Inc. (Maxim Integrated) for safeguarding low-voltage systems. It protects against voltage faults up to +28V, automatically turning off an internal nFET switch when the input voltage exceeds the overvoltage threshold or drops below the undervoltage threshold.

 

Key features include a low 100mΩ typical on-resistance, minimum 1.5A current-limit protection with autoretry mode for short circuits, and integrated low-capacitance (3pF) ESD protection suitable for high-speed USB 2.0 signals. The device has a preset overvoltage threshold of 6.15V and an undervoltage threshold of 2.55V.

 

This controller operates within an extended temperature range of -40°C to +85°C and is housed in a compact 2mm x 3mm, 8-pin TDFN package, making it suitable for space-constrained applications like cell phones and media players. The device also includes thermal-shutdown protection.

 

Mounting is via surface mount technology. The operating temperature range is -40°C to +85°C, with a junction temperature limit of +150°C and a storage temperature range of -65°C to +150°C.
