ADM1041ARQ-REEL

The ADM1041 series are secondary-side and management IC specifically designeds to minimize external component counts and to eliminate the need for manual calibration or adjustment on the secondary-side controller. The principle application of this IC is to provide voltage control, current share, and housekeeping functions for single output in N+1 server power supplies.The ADM1041 series is manufactured with a 5 V CMOS process and combines digital and analog circuitry. An internal EEPROM provides added flexibility in the trimming of timing and voltage and selection of various functions. Programming is done via an SMBus serial port that also allows communication capability with a microprocessor or microcontroller.The usual configuration using this IC is on a one per output basis. Outputs from the IC can be wire-ORed together or bused in parallel and read by a microprocessor. A key feature on this IC is support for an OrFET circuit when higher efficiency or power density is required.

Features of the ADM1041 series are:(1)Digital calibration via internal EEPROM;(2)Supports SSI specification;(3)Comprehensive fault detection;(4)Reduced component count on secondary side;(5)Standalone or microcontroller control.

The absolute maximum ratings of the ADM1041 series can be summarized as:(1)Supply Voltage (Continuous), VDD:6.5 V;(2)Data Pins SDA, SCL, VDATA:VDD + 0.5 V,GND - 0.3 V;(3)Continuous Power at 25°C, PD-QSOP24:450 mW;(4)Operating Temperature, TAMB:-40°C to +85°C;(5)Junction Temperature, TJ:150°C;(6)Storage Temperature, TSTG:-60°C to +150°C;(7)Lead Temperature(Soldering, 10 Seconds), TL:300°C;(8)ESD Protection on All Pins, VESD:2 kV;(9)Thermal Resistance, Junction to Air, JA:150°C/W;(10)ICT Source Current:7 mA.
