        • Battery Sensor ICs

        • IDT’s battery sensor 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.

          Battery Charge Measurement in Automotive Applications

          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. IDT’s battery sensor ICs can achieve this requirement by means of a shunt-resistor-based current measurement technique combined with a highly dynamic embedded programmable gain amplifier.

Our sophisticated calibration and configuration techniques significantly reduce external component count and time-to-market for products that meet new emission-reduction standards.

        About Sensor Signal Conditioners

        Most analog signals require some form of preparation before they can be digitized. Sensor signal conditioning is the manipulation of a sensor signal in a way that prepares it for the next stage of processing. IDT’s sensor signal conditioner ICs typically interface with two main sensor types: resistive bridges and differential capacitors. For each sensor type, further specialization allows selecting the optimal balance between price and performance for the required operating voltage and temperature range, gain, resolution, input/output format, and qualification level. IDT’s SSC ICs offer digital compensation of sensor offset, sensitivity, temperature drift, and nonlinearity in wide operational temperature ranges.

Designed for high resolution altimeter module applications, theZSSC3016 can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal. Developed for correction of resistive bridge sensors, it can also provide a corrected temperature output measured with an internal sensor. The measured and corrected bridge values are provided at the digital output pins, which can be configured as I2C (≤ 3.4MHz) or SPI (≤ 20MHz). Digital compensation of signal offset, sensitivity, temperature, and non-linearity is accomplished via an 18-bit internal digital signal processor (DSP) running a correction algorithm. Calibration coefficients are stored on-chip in a highly reliable, nonvolatile, multiple-time programmable (MTP) memory. Programming the ZSSC3016 is simple via the serial interface and the PC-controlled calibration software provided in the IDT Evaluation Kit. The interface is used for the PC-controlled calibration procedure, which programs the set of calibration coefficients in memory. Digital mating of the sensor with the signal conditioner is fast and precise, eliminating the overhead normally associated with trimming external components and multi-pass calibration routines.

                                  • The ZSPM4121 battery management load switch can be used to protect a battery from excessive discharge. It actively switches the battery power source off if it drops to a set threshold (Off Mode). When the input battery voltage is above the threshold, the load switch is on (On Mode). The ZSPM4121threshold voltage (VTHRESH) is programmed at manufacturing to a set point in the range of 1.2V to 4.2V with 100mV steps between options. When the input battery voltage has been switched off by the ZSPM4121, the quiescent current draw on the battery is in the order of 100pA (typical). The quiescent current in the on state is as low as 70nA. The ZSPM4121 consists of an internally generated threshold voltage, a comparator with hysteresis, slew rate control for the load switch, a P-channel load switch, and an open-drain indicator pin. The 500mV hysteresis between the Off Mode and the On Mode prevents intermittent operation. The ZSPM4121 also provides over-current protection.

                                  • The ZSPM4521 is a DC/DC synchronous switching lithium-ion (Li-Ion) battery charger with fully integrated power switches, internal compensation, and full fault protection. It uses a temperature-independent photovoltaic maximum power point tracking (MPPT) function to optimize power output from the source during Full-Charge Constant-Current (CC) Mode. Its switching frequency of 1MHz enables the use of small filter components, resulting in smaller board space and reduced bill-of material costs. During Full-Charge Constant-Current Mode, the duty cycle is controlled by the MPPT regulator. Once the battery’s termination voltage is reached, the regulator operates in Constant Voltage Mode. In this mode, the ZSPM4521 modulates the charging current until the battery reaches full charge. When the regulator is disabled (the EN pin is low), the device draws 10µA (typical) quiescent current (Disabled Mode). TheZSPM4521 includes supervisory reporting through the NFLT (inverted fault) open-drain output to interface other components in the system. Device programming is achieved by an I²C interface through the SCL and SDA pins.

                                              About Step-down Switching Regulators

                                              A step-down, or buck, switching regulator takes an input voltage and efficiently converts it into a regulated lower voltage. Devices typically come with fixed or adjustable output voltages. A good buck regulator will provide high-efficiency and excellent transient response under all load conditions. Buck regulators will often provide special features to ensure protection of the IC during fault conditions, such as under-voltage lockout, thermal shutdown, soft-start, currently limiting, and short-circuit protection.
