Description

The AAT4625IKS-1-T1 is an electronic component classified as IC Chips. It is a smart switch P-channel MOSFET power switch that is designed for high-side load-switching applications in PCMCIA GSM/GPRS/3G modem cards. It is designed to prevent exceeding power ratings of the PCMCIA host by being used in conjunction with a super capacitor. Its features include two independent, programmable current limits, a power loop, and reverse current blocking protection. It has low quiescent current, only requires 1.4V for enable control pin, and has under-voltage lockout. The AAT4625IKS-1-T1 is available in a 12-Pin TSOPJW package and can operate within a temperature range of -40°C to 85°C.
