AP1703DWL-7

AP1703DWL-7 is a power management integrated circuit (PMIC) that\'s specially designed to provide excellent performance in situations where small and cost effective solutions are paramount. As one of the Supervisors class of ICs in PMICs, it is primarily used by computer engineers and electronics hobbyists to monitor system voltage. In this article, we will discuss the application fields and working principles of AP1703DWL-7.

The AP1703DWL-7 Supervisor IC from Diodes Incorporated is designed to provide accurate voltage monitoring and reset control for battery-powered portable electronic devices. It helps to monitor and regulate the power on battery-powered applications, ensuring that the battery does not fall below a safe level or exceed the maximum allowable voltage level. It can also provide a power-on reset (POR) signal to the processor or other logic circuits during power-up of the system, ensuring that the processor and other logic circuits start up from a known state.

AP1703DWL-7 is also used in a number of sensor applications, where its built-in analog comparators are used to detect high and low threshold levels in analog signals. This can be used to monitor pressure, voltage, current or temperature in a wide range of applications. It also features two integrated N-channel FETs, one of which can be used to provide over voltage protection, while the other can be used to switch power on and off, or to control a user interface such as a LED or LCD display.

AP1703DWL-7 integrates three independent monitor rails and has a wide input voltage range from 2.7 V to 5.5 V and an adjustable output voltage (reset trip point). It also has a high accuracy reference of 2.5V and a low power consumption of 0.7 μA typical at 3.3V. It is available in the industry standard SOT-23-5 and SOIC-8 packages, making it ideal for space-constrained applications, making it the perfect choice for mobile or consumer electronic applications.

When using the AP1703DWL-7, the main power supply is connected to the VDD pin. The reset (RES) pin is connected to the processor or other logic circuits, while the output monitor pins (OUT1/OUT2/OUT3) are connected to logic circuit blocks such as counters, timers and sensors. The output enable pin (OE/EN) is used to enable or disable the monitor outputs. When the output enable pin is set to high, the output pins will be enabled, otherwise the output pins will be disabled.

The AP1703DWL-7 also has an integrated comparator, which is used to detect high and low threshold levels in analog signals. An externally-generated reference voltage is connected to REF and one of the output monitor pins (OUT1/OUT2/OUT3) is connected to a signal that needs to be monitored. When the monitored signal reaches the user-defined threshold voltage on the REF pin, the output pin on the AP1703DWL-7 will be set (logic 1) or reset (logic 0), depending on if the monitored signal goes above or below the reference voltage.

In summary, AP1703DWL-7 is an advanced power management integrated circuit that can be used in battery-powered devices and sensor applications. It integrates three independent monitor rails and has an adjustable output voltage (reset trip point). It also offers a number of advantages over traditional reset circuits, including a high accuracy reference and low power consumption. It is available in the industry-standard packages making it ideal for space-constrained applications, making it the perfect choice for mobile or consumer electronic applications.
