A Power Management Integrated Circuit (PMIC) is an electronic circuit designed to provide power to a variety of components, such as processors, memories, analog and digital circuits and peripherals in a computer system. Supervisors are one of the important subclasses of PMICs. MC34160PG is a type of supervisor that is specifically designed for automotive applications. This article will discuss the application field and working principle of MC34160PG supervisor.

The MC34160PG is a two-channel supervisor with Watchdog, reset, reference and power fail functions. It is designed to monitor both system and power supply voltages in automotive applications. The device has two independent voltage supervision channels, each of which can compare two voltage thresholds with a voltage range of 1.9V to 27V. The main features of the MC34160PG include precision threshold control with hysteresis of 10mV, tolerance on reset indicating capability with 100ms reset delay time, Watchdog time out with 13.5ms resolution, adjustable reset active time of 150ms, fast reset active time of 200µs max and wide operating temperature range of -40°C to +125°C.

The reset function of the MC34160PG supervisor is triggered either when the internal Watchdog timer expires or when the voltage on the supply pin rises below the Under Voltage Lockout threshold of 3.2V. When the voltage falls below VPOR threshold, the Watchdog timer is disabled and the reset signal is asserted. This reset signal then moves a few millivolts across two switches to start latching the reset output pin to logic low. After the falling voltage rise over the reset threshold, the reset state is released and the output is latched to logic high.

In addition to the reset function, the MC34160PG also provides reference, watchdog and power failure functions. The device has an internal voltage reference that can be used to power other components in the system.The Watchdog timer monitors the levels of the external resolver, oscillator or microcontroller to ensure that they do not become out of sync with the system clock. If they do, the reset signal is triggered.The power failure output can detect any unexpected power loss and provide logic low output without relying on external components.

The MC34160PG supervisor is used in a variety of automotive applications, including automotive infotainment systems, battery management systems, powertrain control modules, and ignition systems.The device is ideal for these applications as it has been designed to handle automotive environmental challenges, such as wide temperature ranges, wide supply voltage variations, and transients. The supervisor also offers high efficiency, low quiescent current, short response time and low voltage operation.

In summary, the MC34160PG supervisor is a two-channel supervisor designed for automotive applications. It is capable of monitoring both system and power supply voltages. It provides reset, reference, watchdog and power fail functions, which are highly beneficial for automotive applications. The device is known for its high efficiency and low power consumption, making it suitable for use in energy-saving applications. This supervisor is an ideal choice for automotive systems that require reliable performance and long-term reliability.
