Q & A
- What is the primary function of the STM6710JWB6F?
The primary function of the STM6710JWB6F is to monitor up to four different supply voltages and assert a system reset if any of the monitored voltages fall below their respective minimum thresholds.
- What are the available reset threshold options for the STM6710JWB6F?
The STM6710JWB6F offers factory-set reset threshold options for 1.8 V, 2.5 V, 3.0 V, 3.3 V, and 5.0 V supplies with -5% and -10% tolerances.
- What is the typical reset timeout period for the STM6710JWB6F?
The typical reset timeout period for the STM6710JWB6F is 200 ms.
- How does the RESET output of the STM6710JWB6F behave?
The RESET output is an open drain, active low output that asserts low whenever a monitored supply voltage falls below its minimum threshold. It remains low for the reset timeout period before going high.
- What is the power consumption of the STM6710JWB6F?
The power consumption of the STM6710JWB6F is less than 35 µA.
- Is the STM6710JWB6F immune to power supply transients?
Yes, the STM6710JWB6F is designed to be immune to brief power supply transients.
- What package type is the STM6710JWB6F available in?
The STM6710JWB6F is available in a 6-pin SOT23 package.
- Is the STM6710JWB6F RoHS compliant?
Yes, the STM6710JWB6F is RoHS compliant.
- What are some common applications of the STM6710JWB6F?
Common applications include telecommunications equipment, set-top boxes, networking equipment, server/workstations, desktop and notebook computers, and data storage equipment.
- How can the reset threshold voltage be adjusted for the STM6710JWB6F?
The reset threshold voltage can be adjusted using an external resistor divider network connected to the VxIN pins to set the trip point to a desired voltage above 620 mV.
