ZMDI’s Battery Monitoring ICs
Enable Energy Efficiency
Due to the urgent global need to reduce
environmental pollution and to meet governmental regulations limiting maximum harmful emission
from vehicles, automotive companies are increasing
their efforts to introduce features aimed towards
reducing fuel consumption.
One of these highly effective fuel saving features
is the start-stop system, which automatically shuts
down and restarts the engine as needed to reduce
the amount of time the engine spends idling,
thereby reducing fuel consumption and emissions
by as much as 5 to10 percent. In order to ensure a
safe re-start of the engine once it has been turned
off, precise information on the charge condition of
the starter battery is essential.
ZMDI’s battery monitoring ICs accurately determine
the charge condition of the battery based on inputs
including charge and discharge currents, battery
voltage, temperature, and aging. Both voltage
and current are measured with two highly linear,
synchronous 24-bit analog-to-digital converters.
Measuring charge and discharge currents is
particularly challenging as the battery monitoring IC
must be capable of precisely measuring milliampere
currents when the engine is turned off and up to
more than one thousand amperes when the engine
is started. ZMDI’s battery monitoring ICs can achieve
this requirement by means of a shunt-resistor-based
current measurement technique combined with
a highly dynamic embedded programmable gain
amplifier.
Another challenging requirement is for ultra-low
power consumption in standby mode, for example
when a vehicle is parked. The battery monitoring IC
must continue to monitor the battery’s state even
when the engine is turned off. In this standby mode,
our battery monitoring ICs typically consume only 55
to 60 μA.
Applications for
ZMDI Battery Management ICs
• Lead-acid battery monitoring
• Battery monitoring for energy storage;
e.g., in photovoltaic installations
• Intelligent sensors and sensor interfaces
• Electric energy measurement and monitoring

Battery Monitoring ICs with
Internal and External Microcontrollers
ZMDI offers two product lines for battery monitoring ICs: one for external microcontrollers and a
more advanced line with an integrated 32-bit ARM©
Cortex™ based microcontroller.*
Our leading-edge ICs with an internal microcontroller
are preferred for small form-factor, standalone
intelligent battery monitoring systems. Our battery
monitoring ICs for use with external microcontrollers
are preferred for solutions that are embedded
in systems that already contain a microcontroller
or where one master controller controls several
battery monitoring slaves, such as in multi-battery
applications or systems requiring additional safety
via redundant measurement of battery current.
ZMDI’s ICs with an internal microcontroller offer
effective intellectual property safeguarding for
customer software by employing copy protection
for the user’s firmware on the chip.
Key Features
Intelligent Battery Sensor ICs
• Wide operating temperature: -40°C to +125°C
• High-Precision 24-bit sigma-delta ADC
(18 bits with no missing codes)
• On-chip voltage reference (5ppm/K)
• External or internal, factory-calibrated
temperature sensor
• Small PQFN packages: 5x5mm or 6x6mm
• 32-bit ARM® Cortex™-M0* microcontroller
Highly Efficient Analog ICs

Data Acquisition System Basis Chip (SBC)
ZSSC1750/51
Data Acquisition System Basis Chip (SBC)
Brief Description
Benefits
The ZSSC1750 and ZSSC1751 are System Basis
Chips (SBCs) with a dual-channel ADC for battery
sensing/management in automotive, industrial, and
medical systems. The ZSSC1750 and ZSSC1751
feature an SPI interface; in addition, the ZSSC1750
has an integrated LIN 2.1 transceiver.

One of the two input channels measures the battery
current IBAT via the voltage drop at the external shunt
resistor. The second channel measures the battery
voltage VBAT and the temperature.
By simultaneously measuring VBAT and IBAT, it is
possible to determine dynamically the internal
resistance of the battery, Rdi, which is correlated
with the state-of-health (SOH) of the battery. By
integrating IBAT, it is possible to determine the stateof-charge (SOC) and the state-of-function (SOF) of
the battery.
During Sleep Mode, the system makes periodic
measurements to monitor the discharge of the
battery. Measurement cycles are controlled by user
software and include various wake-up conditions.
The ZSSC1750/51 is optimized for ultra-low power
consumption drawing only 60µA or less in this mode.

Intelligent Battery Sensor IC
Brief Description
Benefits
The ZSSC1956/ZSSC1856 ICs are dual-channel
ADCs with an embedded microcontroller for battery
sensing and management in automotive, industrial,
and medical systems. One of the two input channels
measures the battery current IBAT via the voltage
drop at the external shunt resistor. The second input
channel measures the battery voltage VBAT and the
temperature. An integrated flash memory is provided
for customer-specific software; e.g., dedicated algorithms for calculating the battery state.

During Sleep Mode (e.g., engine is off), the system
makes periodic measurements to monitor the discharge of the battery. Measurement cycles are controlled by the software and include various wake-up
conditions. The ZSSC1956/ZSSC1856 ICs are optimized for ultra-low power consumption and draw
only 100µA or less in Low-Power Mode. The
ZSSC1956 is AEC-Q100-qualified for automotive
applications including harsh environments.

ZSPM4121
Under-Voltage Load Switch for Smart Battery Management
ZSPM4121
Under-Voltage Load Switch for Smart Battery Management
Brief Description
Features
The ZSPM4121 battery management load switch
can be used to protect a battery from excessive
discharge. It actively monitors the battery voltage
and disconnects the battery from the load if the
battery drops below a set voltage threshold. When
the input battery voltage reaches 500mV above the
set voltage threshold, the load switch turns on and
connects the battery to the load. The 500mV
hysteresis between the Off Mode and the On Mode
prevents intermittent operation.

The voltage threshold (VTHRESH) can be programmed
at manufacturing to a customer-selected set point in
the voltage range of 1.2V to 4.2V in 100mV increments to support a wide range of applications in consumer, medical, portable, and industrial applications.
This device has ultra-low quiescent current, which
makes it ideal for battery-powered applications.
Typical quiescent current is 100pA in the Off Mode
and 70nA in the On Mode.
The ZSPM4121 includes a slew rate control P-channel load switch, over-current protection, and an
open-drain power indicator pin (NPG). The slew-rate
controlled turn-on characteristic prevents inrush
current and voltage droop on the voltage. The overcurrent limit protects the device in case of an
overload, short-circuit, or ground fault event.
