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 I
2
C 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.

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 r
DS(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

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)
