New IntelliMAX™ Series Addresses Low-Power Requirements for Ultra-Portable Products

IntelliMAX™, the first in a series of advanced load management devices addresses the low power requirements for Ultra Portable products.

IntelliMAX™ integrates the most features in one single SC-70 package: approach simplifies designs and speed time-to-market

Fairchild's IntelliMAX™ devices offer a unique combination of protection, control and fault monitoring features in one low-profile SC-70 package by replacing multiple active and passive components used in traditional analog IC control functions and MOSFET power switch approaches. Each FPF200X load switch includes controlled switch turn-on, current limiting with 50mA or 100mA options, under-voltage lockout and thermal shutdown. Also included are a flag for fault conditions with options for fault blanking, and auto-restart functions-all with 4KV ESD protection. Additionally, IntelliMAX features low-shutdown current (<1 uA) to conserve battery life, and a fast current limit response time (3 us for nominal over-current conditions, 20ns for hard short conditions) for safety/fault protection.

Features and Benefits

- Wide operating voltage range: 1.8-5.5V Vdc operating, 6V (absolute max)
- Controlled switch turn-on reduces in-rush current and supply transients
- Integrated current-limiting with device options: 50mA and 100mA
- Under-voltage lockout - nominal 1.6V, with typical hysteresis of 50mV and 100mA
- Thermal shutdown to reduce excessive heating or system damage
- Fast current limit response time: (3uS for nominal over-current conditions, 20nS for hard short conditions)
- Flag for fault conditions with options for fault blanking, auto-restart functions to simplify fault condition management
- Small high-volume capable SC70 SMD package available with Pb-free option
- <1uA shutdown current-conserving critical battery life
