bq24230H and bq24232H 0.5-A Single-Chip Li-Ion
This user’s guide describes the bq24230H (PREVIEW) and bq24232H (bqTINY-III™) evaluation module
(EVM). The EVM provides a convenient method for evaluating the performance of a charge management
and system power solution for portable applications having 4.35-V Li-Ion batteries using either the
bq24230H and bq24232H products. A completely designed and tested module is presented. The charger
is designed to deliver up to 0.5 A of continuous current to the system or charger for one-cell Li-ion or Lipolymer applications (see the data sheet for the correct device) using a DC power supply. The charger is
programmed by the factory to deliver 0.5 A of charging current. This EVM was designed as a standalone
evaluation module, but it can also be interfaced with the system and host via the connectors and headers.

Introduction

Introduction
The bq2423xH family powers the system while independently charging the battery. This feature reduces
the charge and discharge cycles on the battery, allows for proper charge termination, and allows the
system to run with an absent or defective battery pack. This feature also allows for the system to
instantaneously turn on from an external power source even when using a deeply discharged battery
pack.
This charger family has one input and can be programmed to be used with an adapter or USB port as the
power source for the system. In the USB configuration, the host can select from the two preset input
maximum current limits of 100 and 500 mA. The charger dynamically adjusts the charge rate based on
the system load to stay within the 100-mA or 500-mA maximum limits. An external resistor, RSET1, sets
the magnitude of the charge current between 25 and 500 mA. If the charge current exceeds the available
input current, the voltage on the OUT pin drops to the DPPM threshold or the battery voltage, whichever is
higher. The charging current is reduced to what current is available (IBAT = IIN – IOUT).
The integrated circuit (IC) charges the battery in three phases: conditioning, constant current, and
constant voltage. Charge is terminated based on minimum current. A resistor-programmable charge timer
provides a backup safety for charge termination. The charge automatically restarts if the battery voltage
falls below an internal threshold. Sleep mode is entered when the supply is removed (Vin drops to the
battery voltage). Pin 15 of bq24230H has a TD pin that allows the user to disable termination (as well as
safety timers) at startup. Pin 15 of the bq24232H is ITERM, which allows the user to set the termination up
to 50% of the fast charge current instead of the default 10% value.

The two potential sources to power the system (VOUT) are the input source and the battery (adapter or
USB port). The IC is designed to power the system continuously. If the adapter or USB input is not
available (or disabled), the battery connects to the system.
In the thermal regulation condition (TJ = 125°C, not a first-choice design mode of operation), the charge
current is reduced to the battery, and the system still gets its power from the input. The battery
supplement is available in thermal regulation if the VOUT falls to VBAT. In thermal cutoff (approximately
155°C), the input sources are disconnected, but the internal battery FET connects the battery to VOUT.

Test Summary
2.1
www.ti.com
Performance Recommendations
This IC is a linear battery charger and also powers the system from the input through the linear regulator
output. Being a linear device, the charger is most efficient when the input voltage is only slightly above the
battery voltage (VIN = 4.75 to 5.5 V). Too low of an input voltage (less than the OUT voltage plus the
dropout voltage) results in degraded performance. Excessive input voltage (> 5.5 V) results in excess
power dissipation and reduced performance (that is, reduced charge current) due to the IC's thermal
regulation protection circuit. The IC is rated to 28 V and is not damaged with VIN voltages less than this,
but any VIN voltage over the overvoltage protection (OVP) threshold disables the IC. Thus, the
recommended operating range for maximum performance is between 4.75 and 5.5 V, with a preference
for the lower values.

Test Procedure
1.
2.
3.
4.
Verify that the equipment and EVM is setup according to the preceding section.
Verify that VOUT is approximately equal to VBAT.
Turn on P/S number 1, +5.25-Vdc supply to the UUT.
Verify VBAT is between 2.4 and 3 Vdc, and the charger is in precharge state: LEDs CHG (D1) and
PGOOD (D2) are on. If VBAT is above the low-voltage threshold (V(LOWV) approximately 3 V), then the IC
is in fast-charge mode. If the IC is in fast charge, skip step 7.
5. Verify DMM number 3, IBAT is approximately 5 mV or approximately 0.05 A.
6. Verify that VOUT for bq2423XH is 4.4 to 4.6 V.
7. Allow the battery to charge until VBAT is between 3.3 and 4 Vdc. The charger delivers the programmed
constant current to the battery unless the input cannot source the required current.
8. Verify IBAT is approximately 50 mV or approximately 0.5 A (for a 1.74-kΩ resistor on ISET).
9. Set JMP5 (EN1) to HI, and verify that the chip is disabled, D1 (CHG) is turned off, and the P/S number
1 current has dropped to 0. The internal battery FET must be on, connecting the BAT pin to the OUT
pin. Verify that the voltage on the OUT pin is close to the battery voltage. See Figure 2 for EN1/2
modes of operation.
10. Set JMP4 (EN2) to VSS. Verify that the input current is less than 500 mA (USB 500-mA mode). If the
input current is restricted due to USB mode, or if the adapter is current limiting, the OUT pin drops in
voltage and enters the DPM mode, if the system current is less than the restricted input current. This
IC must be in DPM mode with the system voltage at the DPM.
11. Set JMP5 (EN1) to VSS and verify USB 100-mA mode. The system load is more than the allowed 100
mA on the input, so the OUT voltage drops to the battery voltage, and the battery FET is switched on
and supplements the input current. Verify that VOUT has dropped just below the battery voltage and the
battery is supplying IBAT, approximately (VOUT / 10 Ω – 100 mA).
12. Set JMP4 (EN2) to HI to return to the ISET mode where the programmed current is approximately
0.5 A.
13. Set JMP3 to HI, and verify that the charging is disabled and that the CHG LED (D1) turns off. Verify
that the system is still powered by the input.
14. Set JMP3 to VSS, and verify that charging continues and that D1 turns on.
15. Record the OUT voltage and battery charge current. Adjust R8 CCW until the input current starts to be
reduced (about 2 turns). Note how the OUT voltage drops and the charge current is reduced as the
input current limit loops kicks in and limits the input current. Adjust R8 to its original position.
16. On the bq24230H IC, set JMP2 HI, and verify that the BAT FET turns off and allows no charging or
discharging of the battery.
17. Adjust the R16 (TS-Pot) up or down until the TS threshold is reached. Verify that the charging current
is disabled. Return the TS resistance within the normal range and verify the continued charging
operation.
18. Allow the battery to continue to charge until the battery reaches voltage regulation, approximately 4.2
V ±40 mV. Verify that the voltage is regulated as the current tapers over the next 1 to 2 h depending
on the battery capacity. See Figure 3 for a charge profile (time in plot is not proportional to actual
charge time).
19. Verify that the current tapers to about 50 mA (5 mV on DMM number 3) when termination occurs. Note
on the bq24230H IC that termination can be disabled by setting the TD pin HI (JMP2). Also note that
on bq24232H, the ITERM resistor (R10) can adjust the termination threshold.
20. Verify that the LED, D1, turns off and the current drops to 0.
21. Turn off P/S number 1, and allow the system load to discharge the battery until a refresh charge is
initiated. Verify that the battery voltage dropped to approximately 4.1 V.
22. Verify that the LED, D1, did not turn on for the refresh cycle.
This concludes the procedure for demonstrating the features of this power path charger. For more detailed
explanations and instructive waveforms, see the data sheet.
