General Description

The APR3011/2/3 are designed to monitor voltage supplies in µP and digital systems. The quiescent current is extremely low, typically 1.5 µA, making it ideal for portable battery operated equipment. The APR3011/2/3 operate by monitoring the system power supply voltage. When the input voltage drops below a fixed threshold, the device asserts a reset signal for a fixed time period after Vcc rises above the fixed threshold. The APR3011/2/3 series is available with three output stage versions : APR3011 push-pull active low output, APR3012 push-pull active high output and APR3013 open drain active low output. They are also designed to reject fast line transient glitches on Vcc. The APR3011/2/3 are come in a miniature SOT-23, SOT-23-5, SOT-89 packages.

Application Information

VCC Transient Rejection

The APR301 1/2/3 have the function to reject the transient glitches from the power line. The Maximum Transient Duration vs. Reset Threshold Overdrive shows at Typical Characteristics.The transient voltage with

the duration under the curve will not generate a reset signal, e.g. a transient of 100mV below the reset threshold voltage have the duration more than 35us, it will generate a reset signal. Connect a 0.1uF bypass capacitor to the VCC pin can improve the transient immunity.

Reset Output

The APR3011/2/3 have 3 output stage versions: APR3001 is an active low push-pull output, when the VCC drops below the reset threshold, the RESET output generates a low signal. APR3012 is an active high push-pull output, when the VCC drops below the reset threshold, the RESET output generates a high signal (see Timing Chart). APR3013 is an active low open drain output, the RESET output must be connected a pull-up resistor to a supply voltage that is lower than 6V, it suits to use in multiple voltage systems (see Figure 2). The APR301 1 RESET output is valid until the VCC=1.2V, below 1.2V the IC is shutdown, and the output becomes a floating state. If it is a trouble, a resistor should be connected from reset output to ground to keep the reset output low (see Figure 1). For The APR3012, a pull-up resistor to VCC is required to keep the valid reset output for VCC below 1.2V.
