Introduction to MAX6388XS42D3-T

The MAX6388XS42D3-T is a high efficiency, low quiescent current microprocessor voltage supervisor specifically designed for use in automotive and industrial applications. The device is available in a tiny 2.5 mm x 3 mm, 8-pin leadless chip scale package (LCCSP). The integrated dual-input microprocessor voltage supervisor provides a servo loop that is designed to operate over wide input voltage, temperature and load current ranges. The MAX6388XS42D3-T has two comparators that can be used to monitor two separate voltage rails. The device can monitor logic, memory, and other power supplies.

The servo loop on the MAX6388XS42D3-T allows the device to maintain a constant output voltage over varying input voltage and temperature ranges, even when there is a large load current. The device also features integrated clock synchronization and adjustable current limitation, as well as a selectable power-up/power-down reset delay. In addition, the device includes an integrated watchdog timer that can be used to detect a wide-range of faults, reducing design complexity and cost.

Application Fields

The MAX6388XS42D3-T is suitable for use in a wide range of automotive and industrial applications, including powertrain, body/interior electronics, and safety-critical systems. It also supports advanced safety protocols such as ISO 26262. It can be used in safety-critical applications such as engine control, steering control, battery management, powertrain control, and transmission control. Additionally, the device supports battery management systems (BMS) and advanced driver assistance systems (ADAS). The device is designed to interface with a wide range of microcontrollers, including 8, 16, 32, and 64-bit MCUs.

The MAX6388XS42D3-T is designed to be used in harsh automotive environments. It can operate at temperatures ranging from -40°C to 125°C, as well as in situations with transient conditions due to load changes. The device is also designed for EMI/EMC compliance and immunity to ESD and surge risk, making it ideal for automotive applications.

Working Principle

The MAX6388XS42D3-T features a voltage supervisor, which has a set of comparators that can detect when the input supply voltage has exceeded a certain threshold. The device will then generate a reset signal to alert the system of the overvoltage condition. The comparators can be configured to monitor one or two separate voltage rails, depending on the application’s requirements. The input supply voltage is monitored by an internal analog-to-digital converter (ADC), which converts an analog input voltage to a digital signal that can be monitored by the processor.

In addition to the voltage supervision, the device also provides an integrated watchdog timer. This feature can be used to detect a wide range of faults, including power-on reset, clock frequency problems, and brownout conditions. The device also supports clock synchronization and adjustable current limitation. The adjustable current limiting can be used to prevent the device from drawing more current than necessary, reducing power dissipation and increasing efficiency.

The MAX6388XS42D3-T features a wide operating voltage range and can operate from 2.5V to 17V. It provides an adjustable reset threshold and a wide temperature range, from -40°C to 125°C. The device is available in a tiny 2.5 mm x 3 mm, 8-pin leadless chip scale package (LCCSP) and includes an integrated reset output.

Conclusion

The MAX6388XS42D3-T is a high efficiency, low quiescent current microprocessor voltage supervisor designed for automotive and industrial applications. The integrated dual-input microprocessor voltage supervisor provides a servo loop that is designed to operate over a wide variety of input voltage, temperature, and load conditions. The device is suitable for use in harsh automotive environments and supports advanced safety protocols.
