Smart Battery Charger with SMBus Interface

The Smart Battery (SB) contains circuitry which pro-

vides charging information to the SBC. The SBC

receives this information in terms of ChargingVoltage(),

ChargingCurrent(), and AlarmWarning() commands

from the SB. The SBC and SB communicate via the

System Management Bus (SMB), which is an imple-

mentation of the I C bus (refer to "The Smart Manage-

INTRODUCTION

ment Bus Speciﬁcation," Intel; and "The I C Bus and

How to Use It," Philips Semiconductor). The SBC sets

the charging current and voltage based on input from

the SB. The SBC charger also has the intelligence to

monitor the SB’s thermistor. The thermistor provides

temperature information for charge termination, and

battery chemistry information.

This application note provides the schematics, software

listings, and circuit board layout for a PIC16C73 based

Smart Battery Charger. The Demo Board, DC101, is

available to selected customers through Linear Tech-

nology Corp. product marketing.

The DC101 (Figure 1) is the Smart Battery Charger

(SBC) portion of a Smart Battery System. A simpliﬁed

block diagram of a Smart Battery System is shown in

Figure 3 (refer to "The Smart Battery Charger Speciﬁ-

cation," Duracell).
