MAX1645A Evaluation Kit/Evaluation System
General Description
Features
The MAX1645A evaluation system (EV system) consists
of a MAX1645A evaluation kit (EV kit) and a companion
Maxim System Management Bus (SMBus™) interface
board. The EV kit simplifies evaluation of the MAX1645A
chemistry-independent Level 2 smart battery charger.
♦ Charges Any Battery Chemistry: Li+, NiCd, NiMH,
Lead Acid, etc.
♦ SMBus-Compatible 2-Wire Serial Interface
♦ 3A (max) Battery Charge Current
♦ Up to 18.4V Battery Voltage
The Maxim SMBus interface board (MAXSMBus) allows
an IBM-compatible personal computer to use its paral-
lel port to emulate an Intel SMBus 2-wire interface.
Windows 95/98® software provides a user-friendly inter-
face to exercise the MAX1645A’s features.
♦ Up to +28V Input Voltage
♦ Easy-to-Use Software Included
♦ Proven PC Board Layout
Order the MAX1645AEVSYS for complete IBM PC-
based evaluation of the MAX1645A. Order the
MAX1645AEVKIT if you already have an SMBus inter-
face.
♦ Fully Assembled and Tested Surface-Mount Board
