Q & A
- What is the operating voltage range of the STM6524AUABDL6F?
The operating voltage range is from 1.65 V to 5.5 V. - How does the Smart Reset™ feature work?
The Smart Reset™ feature ensures that both push-button inputs must be asserted simultaneously for at least the specified delay (tSRC) to trigger a reset. - What are the options for the reset output?
The reset output can be active low or active high, and it can be either push-pull or open drain with an optional internal pull-up resistor. - What is the operating temperature range of the device?
The operating temperature range is from -40 °C to +85 °C. - What package type is the STM6524AUABDL6F available in?
The device is available in a UDFN6 package with dimensions of 1.6 mm x 1.3 mm x 0.55 mm. - Does the device have ESD protection?
Yes, the device has ESD protection with ratings of 2 kV for the human body model, 1 kV for the charged device model, and 200 V for the machine model. - How does the test mode work?
The test mode can be entered by applying a voltage higher than VCC to the SR0 input, and it allows for quick testing without repeating the test mode triggering process. - What is the significance of the internal pull-up resistor option?
The internal pull-up resistor option simplifies the circuit design by eliminating the need for external pull-up resistors on the Smart Reset™ inputs and reset output. - Can the reset pulse duration be controlled?
Yes, the reset pulse duration can be either fully push-button controlled or defined by a factory-programmed output reset pulse duration (tREC). - Is the device RoHS compliant?
Yes, the device is RoHS compliant and comes in an ECOPACK®2 (Halogen-Free) package.
