Applications

APX803L-38SA-7 is well-suited for many applications such as digital consumer electronics, automotive, and low-power IoT applications. It is designed for space-critical applications such as point of sale equipment, touch screens, smart meters, digital storage devices and so on. Besides, this device is used in power management circuits, as well as in power supply and lighting control applications.

Features

The APX803L-38SA-7 is designed for ultra-low voltage applications with guaranteed protection at 0.9V and a Reset Output Voltage of 4V. It has a low quiescent current of 3µA and a low operating voltage of 0.9V. It has a hysteresis voltage of 0.2V and a reset delay of 140ms to make sure quality power management during operation. This device also has an output voltage accuracy of ± 1.0 % and is available in a 10-Pin 3x3 LLP package.

Working Principle

The APX803L-38SA-7 monitors a voltage level that is determined by external resistors. Once the voltage surpasses the setpoint, the device triggers a reset signal and begins monitoring the voltage level again. It can monitor a maximum voltage range of 3.3V to 5V and supports push-pull and open-drain output for the reset signal.

The device will trigger either a LOW active reset signal or a HIGH active reset signal depending on the output circuit’s configuration. When the voltage surpasses the setpoint, the timer starts and the device delivers the reset signal. When the controlled voltage returns to its normal level, the timer will reset and the device will start monitoring the voltage level again.

Benefits

APX803L-38SA-7 offers customers a variety of benefits due to its small size, low quiescent current, and high accuracy. Its small size makes it a perfect fit for space-critical applications while its low quiescent current of 3µA reduces power consumption and makes it suitable for low-power solutions. Furthermore, its accuracy of ± 1.0 % guarantees its ability to protect against overvoltage.
