Frequently Asked Questions
What does the TLV840NADH29DBVR monitor?
The TLV840NADH29DBVR monitors a single power supply rail and generates a reset output signal when the supply voltage drops below the user-set adjustable threshold. This protects microcontrollers and digital logic from operating under brownout conditions, preventing unpredictable behavior and data corruption.
Can the reset delay be programmed on the TLV840NADH29DBVR?
Yes, the TLV840NADH29DBVR features a programmable reset delay that allows designers to set the minimum hold time for the reset signal after the supply voltage recovers above the threshold. This flexibility ensures the processor or system has sufficient startup time before the reset is released.
What package does the TLV840NADH29DBVR use?
The TLV840NADH29DBVR comes in a SOT-23-5 surface-mount package with 5 pins, which offers an extremely small PCB footprint. This compact package is ideal for portable devices, wearables, and IoT nodes where board space is at a premium.
Is the TLV840NADH29DBVR suitable for battery-powered applications?
Yes, the TLV840NADH29DBVR is well-suited for battery-powered applications due to its low quiescent current consumption and compact SOT-23-5 package. It provides reliable undervoltage detection as the battery discharges, ensuring controlled system shutdown or reset before the supply falls below safe operating limits.
