The  
bq20z90-V110 monitors capacity change, battery  
impedance, open-circuit voltage, and other critical  
parameters of the battery pack, and reports the  
information to the system host controller over a  
serial-communication bus. It is designed to work with  
the bq29330 analog front-end (AFE) protection IC to  
maximize functionality and safety, and minimize  
component count and cost in smart battery circuits.

High-Resolution, 16-Bit Integrating  
Delta-Sigma Converter  
The Impedance Track technology continuously  
analyzes the battery impedance, resulting in superior  
gas-gauging accuracy. This enables remaining  
capacity to be calculated with discharge rate,  
temperature, and cell aging all accounted for during  
each stage of every cycle.

Primary (1st Level) Safety Features  
The bq20z90-V110 supports a wide range of battery and system protection features that can easily be  
configured. The primary safety features include:  
•
•
•
•
•
•
•
•
Battery cell over/under voltage protection  
Battery pack over/under voltage protection

Secondary (2nd Level) Safety Features  
The secondary safety features of the bq20z90-V110 can be used to indicate more serious faults via the SAFE  
(pin 10) pin. This pin can be used to blow an in-line fuse to permanently disable the battery pack from charging  
or discharging. The secondary safety features include:  
•
•
•

Charge FET and Zero-Volt Charge FET fault  
Discharge FET fault  
Fuse blow failure detection  
AFE Communication error  
AFE Verification error  
Internal flash data error  
Charge Control Features  
The bq20z90-V110 charge control features include:  
•
Report the appropriate charging current needed for constant current charging and the appropriate charging  
voltage needed for constant voltage charging to a smart charger using SMBus broadcasts.  
•
Determine the chemical state of charge of each battery cell using Impedance Track™. Using cell balancing  
algorithm, gradually decrease the differences in the cells' state of charge in a fully charged state. This  
prevents high cells from overcharging, causing excessive degradation and also increases the usable pack  
energy by preventing early charge termination.  
•
•
•
•
•
Support Pre-charging/Zero-volt charging  
Support Fast charging  
Support Pulse charging  
Support Charge Inhibit and Charge Suspend modes  
Report charging faults and also indicate charging status via charge and discharge alarms.  
Gas Gauging  
The bq20z90-V110 uses the Impedance Track™ Technology to measure and calculate the available charge in  
battery cells. The achievable accuracy is better than 1% error over the lifetime of the battery and there is no full  
charge-discharge learning cycle required.

LED Display  
The bq20z90-V110 can drive a 3-, 4-, or 5- segment LED display for remaining capacity indication. The LED  
drive current can be adjusted to 3mA, 4mA and 5mA digitally.  
LifeTime Data Logging Features  
The bq20z90-V110 offers a lifetime data logging array, where all important measurements are stored for  
warranty and analysis purposes. The data monitored include:

Authentication  
The bq20z90-V110 supports authentication by the host using SHA-1.  
Power Modes  
The bq20z90-V110 supports 3 different power modes to reduce power consumption:  
•
•
•
In Normal Mode, the bq20z90-V110 performs measurements, calculations, protection decisions, and data  
updates in 1 second intervals. Between these intervals, the bq20z90-V110 is in a reduced power stage.  
In Sleep Mode, the bq20z90-V110 performs measurements, calculations, protection decisions, and data  
updates in adjustable time intervals. Between these intervals, the bq20z90-V110 is in a reduced power stage.  
In Shutdown Mode the bq20z90-V110 is completety disabled.  
CONFIGURATION  
Oscillator Function  
The bq20z90-V110 fully integrates the system and processor oscillators and, therefore, requires no pins or  
components for this feature.  
System Present Operation  
The bq20z90-V110 periodically verifies the PRES pin and detects that the battery is present in the system via a  
low state on a PRES input. When this occurs, bq20z90-V110 enters normal operating mode. When the pack is  
removed from the system and the PRES input is high, the bq20z90-V110 enters the battery-removed state,  
disabling the charge, discharge and ZVCHG FETs. The PRES input is ignored and can be left floating when  
non-removal mode is set in the data flash.

BATTERY PARAMETER MEASUREMENTS  
The bq20z90-V110 uses an integrating delta-sigma analog-to-digital converter (ADC) for current measurement,  
and a second delta-sigma ADC for individual cell and battery voltage, and temperature measurement.  
Charge and Discharge Counting  
The integrating delta-sigma ADC measures the charge/discharge flow of the battery by measuring the voltage  
drop across a small-value sense resistor between the SRP and SRN pins. The integrating ADC measures  
bipolar signals from -0.25 V to 0.25 V. The bq20z90-V110 detects charge activity when VSR = V(SRP)-V(SRN)is  
positive and discharge activity when VSR = V(SRP)-V(SRN) is negative. The bq20z90-V110 continuously integrates  
the signal over time, using an internal counter. The fundamental rate of the counter is 0.65 nVh.  
Voltage  
The bq20z90-V110 updates the individual series cell voltages through the bq29330 at one second intervals. The  
bq20z90-V110 configures the bq29330 to connect the selected cell, cell offset, or bq29330 VREF to the CELL  
pin of the bq29330, which is required to be connected to VIN of the bq20z90. The internal ADC of the  
bq20z90-V110 measures the voltage, scales it, and calibrates itself appropriately. This data is also used to  
calculate the impedance of the cell for the Impedance Track™ gas-gauging.  
Current  
The bq20z90-V110 uses the SRP and SRN inputs to measure and calculate the battery charge and discharge  
current using a 5 mΩ to 20 mΩ typ. sense resistor.  
Wake Function  
The bq20z90-V110 can exit sleep mode, if enabled, by the presence of a programmable level of current signal  
across SRP and SRN.  
Auto Calibration  
The bq20z90-V110 provides an auto-calibration feature to cancel the voltage offset error across SRP and SRN  
for maximum charge measurement accuracy. The bq20z90-V110 performs auto-calibration when the SMBus  
lines stay low continuously for a minimum of a programmable amount of time.  
Temperature  
The bq20z90-V110 TS1 and TS2 inputs, in conjunction with two identical NTC thermistors (default are Semitec  
103AT), measure the battery environmental temperature. The bq20z90-V110 can also be configured to use its  
internal temperature sensor.  
COMMUNICATIONS  
The bq20z90-V110 uses SMBus v1.1 with Master Mode and package error checking (PEC) options per the SBS  
specification.  
SMBus On and Off State  
The bq20z90-V110 detects an SMBus off state when SMBC and SMBD are logic-low for ≥ 2 seconds. Clearing  
this state requires either SMBC or SMBD to transition high. Within 1 ms, the communication bus is available.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in  
a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2)  
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and  
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS  
compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)  
(3)  
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder  
temperature.
