System Basis Chip

ZSSC1750 / ZSSC1751

Datasheet

Brief Description

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 I

BAT

via the voltage drop at the external shunt

resistor. The second channel measures the battery

voltage V

BAT

and the temperature.

By simultaneously measuring V

BAT

and I

BAT

, 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 I

BAT

, it is possible to determine the state-

of-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.

Benefits
