Pin # Pin Name Pin Function Description 1 VSS Ground pin. This is the reference ground for the IC and should be connected to the system ground. 2 NC No Connection. This pin is not internally connected to the IC and can be left floating or unconnected. 3 RESET Active low reset output. This pin goes low when the monitored voltage falls below the threshold, signaling a reset condition for the system. It will stay low until the supply voltage returns to normal. 4 VDD Supply voltage pin. This pin is where the input voltage is applied to power the IC, typically in the range of 1.8V to 5.5V for TLV803S. 5 SENSE Voltage sense input. This pin monitors the system voltage to check if it falls below the set threshold value for triggering a reset. 6 VOUT Output pin used for indicating the system voltage status. It provides a logical signal or an optional output for more advanced configurations.FAQ for TLV803SDBZR
Q: What is the TLV803SDBZR used for? A: The TLV803SDBZR is a voltage supervisor IC used to monitor power supply voltage levels and generate reset signals when the supply voltage is too low.
Q: How many pins does the TLV803SDBZR have? A: The TLV803SDBZR has a 6-pin package, specifically the SOT-23-6 form factor.
Q: What is the recommended supply voltage for TLV803SDBZR? A: The TLV803SDBZR operates within a supply voltage range of 1.8V to 5.5V.
Q: What does the RESET pin do? A: The RESET pin outputs a low signal when the supply voltage drops below the set threshold, indicating a reset condition. It stays low until the voltage returns to a safe level.
Q: What is the purpose of the SENSE pin? A: The SENSE pin monitors the system voltage to detect when it drops below the threshold value, triggering a reset signal.
Q: Can I leave the NC pin unconnected? A: Yes, the NC (No Connection) pin is not internally connected to the IC and can be left floating or unconnected.
Q: What happens when the VDD voltage is too low? A: If the VDD voltage falls below the threshold, the RESET pin will go low to signal a reset condition.
Q: Can I use the TLV803SDBZR in systems with a 5V power supply? A: Yes, the TLV803SDBZR supports a supply voltage range of up to 5.5V, so it can be used with a 5V supply.
Q: How fast does the TLV803SDBZR respond to voltage changes? A: The TLV803SDBZR is designed to respond quickly to voltage dips, and the response time depends on the configuration and the supply voltage change rate.
Q: Is the TLV803SDBZR suitable for battery-powered systems? A: Yes, the TLV803SDBZR is ideal for battery-powered systems due to its low operating voltage and low power consumption.
Q: Can the RESET pin be used to directly drive an external component? A: Yes, the RESET pin can be used to drive external components, such as microcontrollers or other devices, that require a reset signal.
Q: How do I configure the threshold voltage for the TLV803SDBZR? A: The threshold voltage is determined by the voltage applied to the SENSE pin, which monitors the supply voltage level.
Q: What happens if the RESET pin stays low for too long? A: If the RESET pin stays low, the system remains in a reset state, preventing it from operating until the supply voltage returns to normal.
Q: Can I use the TLV803SDBZR in automotive applications? A: Yes, the TLV803SDBZR is suitable for automotive applications as long as the supply voltage is within the specified range and proper conditions are met.
Q: Does the TLV803SDBZR have any over-voltage protection? A: The TLV803SDBZR does not provide direct over-voltage protection but is designed to handle typical operating voltages within the 1.8V to 5.5V range.
Q: How do I connect the TLV803SDBZR to a microcontroller? A: The RESET pin can be connected to the reset input of the microcontroller, while the VDD and SENSE pins should be connected to the system power and voltage monitoring points.
Q: What type of output does the TLV803SDBZR provide? A: The TLV803SDBZR provides a low-active open-drain output for the RESET pin, which can be used to trigger resets or signal status changes.
Q: What is the output impedance of the RESET pin? A: The RESET pin is an open-drain output, meaning it requires an external pull-up resistor to work correctly.
Q: Can the TLV803SDBZR be used for systems with fluctuating voltage? A: Yes, it is designed to monitor voltage and provide reset signals when the voltage fluctuates below the threshold.
Q: How do I handle noisy voltage signals when using the TLV803SDBZR? A: To handle noisy voltage, ensure that the SENSE pin is connected to a stable voltage reference, and consider adding filtering components if necessary.
