Introduction

This user’s guide describes the bq24013 (bqTINY) evaluation module. The

EVM provides a convenient method for evaluating the performance of a

charge-management solution for portable applications using the bq24013

product family. A complete designed and tested charger is presented. The

charger is designed to deliver up to 1.0 A of continuous charge current, but is

programmed for 0.7 A, for single-cell Li-Ion or Li-Pol applications using a dc

power supply.

1.1 Background

The bqTINY series are highly integrated Li-Ion and Li-Pol linear

charge-management devices targeted at space-limited portable applications.

Ina small package,thebqTINY series offerintegrated PowerFET andcurrent

sensor, reverse blocking diode,high-accuracycurrentandvoltageregulation,

charge status, and charge termination.

The bqTINY charges the battery in three phases: conditioning, constant

current, and constant voltage. Charge terminates on the basis of minimum

current. An internal charge-timer provides backup safety for charge

termination. The bqTINY automatically restarts the charge if the battery

voltage falls below an internal threshold and automatically enters sleep mode

when VCC supply is removed.

In addition to the standard features, different versions of the bqTINY offer a

multitude of additional features. These features include temperature-sensing

inputfordetectinghotorcoldbatterypacks,powergood(PG)outputindicating

thepresenceoftheacadapter,aTTL-levelchargeenableinput(CE)todisable

1.2 Performance Specification Summary

This section summarizes the performance specifications of the EVM.

Table 1–1 gives the performance specifications of the EVM.

Table 1–1.Performance Specification Summary

Specification Test Conditions Min Typ Max Units

Input dc voltage, VI(DC) VREG+0.5 5.0 5.2†V

Battery charge current, IO(CHG) See note 0.7 1 A

Power dissipation (V(DC+) –V(BAT+)) ×I(CHG) 1.5 W

†This input voltage maximum is a function of the maximum allowable power dissipation on the IC. The current level is pro-

grammed for 0.7 A. If the programmed charge is changed, then the maximum input voltage must be adjusted.

PmaxIC = 1.5 Watt = ICHG(VDC+ –VBAT+).

Test Summary

This chapter describes the test setups used and the tests performed in evalu-

ating the EVM.

Setup:Thebq24013EVMboardrequiresasingle-cellLi-Ionor Li-Pol battery

pack and a 5-VDC, 1-A power source to provide input power. The test setup

connections and jumper setting selections are configured for a stand-alone

evaluation but can be changed to interface with external hardware, such as a

microcontroller.

2.2 Test Procedure

Setuptheevaluationboardasdescribedabove,bymakingthenecessaryI/O

connections and jumper selections. Before test and evaluation, it is

important to verify that the maximum power dissipation on the IC is not

exceeded: P(MAX) = 1.5 watts.

1) Turn on the power supply, which was preset to 5.0 VDC and 1 A for the

current-limit setting.

2) The bq24013 enters preconditioning mode if the battery is below the

V(LOWV)threshold.Inthismode,thebq24013prechargesthebatterywith

a low current (typically IO(CHG)/10 = 0.7A/10 = 70 mA) until the battery

voltage reaches the V(LOWV) threshold or until the precharge timer

expires. If the timer expires, then the charge current is terminated, the

bq24013 enters fault mode, and both LEDs turn off. Toggling input power

or battery replacement resets fault mode.

3) Once the battery voltage is above the V(LOWV) threshold, the battery

enters fast-charge mode. This EVM is programmed for 0.7 A of

fast-charging current.

4) Once the battery reaches voltage regulation (4.2 V), the current tapers

down as the battery reaches its full capacity.

5) The battery remains at the fast-charge mode until the fast-charge timer

expires,thechargetapertimeexpires,orthechargeterminationthreshold

is reached.

6) If the battery discharges to the recharge threshold, the charger starts fast

charging.

In place of a battery, a source meter that can sink current can easily be

adjusted to test each mode.
