8 to 12 Cell Li-Ion Battery Overcurrent
Protection and Analog Front End Chip Set
The ISL9216 and ISL9217 chipset provides overcurrent
protection and voltage monitoring for multi-cell li-ion battery
packs consisting of 8 to 12 cells. When used together, these
devices provide integrated overcurrent protection circuitry,
short circuit protection, an internal voltage regulator, internal
cell balancing switches, cell voltage level shifters, and drive
circuitry for external FET devices that control pack charge
and discharge. Level shifting of the analog output voltage
from the upper cells and communication between the chips
is handled automatically.
Overcurrent and short circuit thresholds reside in internal
RAM registers and are selected independently via software
using an I2C serial interface. Detection and time-out delays
can be individually varied using internal registers.
Using an internal analog multiplexer, the device provides
monitoring of cell voltage by a separate microcontroller with
A/D converter. Software on this microcontroller implements
all battery control functionality, except for overcurrent and
short circuit shutdown.
Applications

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die attach
materials and 100% matte tin plate PLUS ANNEAL - e3 termination
finish, which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.
Features
• Software selectable overcurrent protection levels and
variable protect detection/release times
- 4 Discharge overcurrent thresholds
- 4 Short circuit thresholds
- 4 Charge overcurrent thresholds
- 8 Overcurrent delay times (Charge)
- 8 Overcurrent delay times (Discharge)
- 2 Short circuit delay times (Discharge)
• Automatic FET turn-off and cell balance disable on
reaching external (battery) or internal (IC) temperature
limit
• Automatic over-ride of cell balance on reaching internal
(IC) temperature limit
• Fast short circuit pack shutdown
• Can use current sense resistor, FET rDS(ON), or Sense
FET for overcurrent detection
• Four battery backed software controlled flags
• Allows three different FET controls:
- Back-to-back N-Channel FETs for charge and discharge
control
- Single N-Channel FET for discharge control
- N-Channel FET for discharge, with separate, optional
(smaller) back-to-back FET for charge
• Chips cascade for packs of 8 to 12 cells
• Integrated charge/discharge FET drive circuitry with
200µA (typ) turn on current and 150mA (typ) discharge
FET turn off current
• 10% accurate 3.3V voltage regulator (35mA out with
external NPN transistor having current gain of 70)
• Cell voltage monitor accurate to within 25mV
• Monitored cell voltage output stable in 100µs
• Internal cell balancing FETs handle up to 200mA of
balancing current for each cell (with the number of cells
being balanced limited by the maximum power dissipation
of 400mW)
• Simple I2C host interface
• Sleep operation with programmable negative edge or
positive edge wake-up
• <10µA sleep mode
• Pb-free (RoHS compliant)
1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

DESCRIPTION
WKUPR Wake-up Upper Device Signal (ISL9216 only). This output wakes up the ISL9217 (upper device) when the output is turned on by the
microcontroller. Once the upper device is awake, this output can be turned off.
SDA Serial Data (ISL9216 only). This is the bi-directional data line for an I2C interface.
SCL Serial Clock. This is the clock line for an I2C communication link.
SDAI
Serial Data Input (ISL9217 only). This pin is a uni-directional I2C serial data input from the ISL9216 to the cascaded ISL9217 device.
This pin connects to the ISL9216 SDAOHV pin.
SDAO Serial Data Output (ISL9217 only). This pin is a uni-directional I2C serial data output to the ISL9216 from the cascaded ISL9217
device. This pin connects to the ISL9216 SDAIHV pin.
SDAIHV Serial Data Input (ISL9216 only). This pin is a uni-directional I2C serial data input from the cascaded ISL9217 device to the ISL9216.
This pin connects to the ISL9217 SDAO pin.
SDAOHV Serial Data Output (ISL9216 only). This pin is a uni-directional serial data output from the ISL9216 to the cascaded ISL9217 device.
This pin connects to the ISL9217 SDAI pin.
SCLHV
HVI2C
Serial Clock Output (ISL9216 only). This pin sends clock pulses from the lower device (ISL9216) to the upper device (ISL9217) for
communication between cascaded devices
HV I2C Reference Voltage (ISL9216 only). This is a reference voltage for the ISL9216 to facilitate the communication link between
cascaded devices. Tie this pin on the ISL9216 to the RGO pin of the ISL9217.
