Product details

4.55V threshold supervisor for 5V rails

The TPS3824-50DBVT is a single-channel voltage supervisor from Texas Instruments, monitoring a 5V rail with a 4.55V threshold. That 0.45V below the nominal rail gives headroom for transient droop without false resets, but still catches a brownout before the processor's logic supply collapses. The output is push-pull, totem pole, and the device supports both active-high and active-low reset assertion, so a single part can drive a /RESET pin (pull low on fault) or a RESET pin (pull high on fault) without an external inverter.

SOT-23-5 package and supply range

The 5-pin footprint is common across the TPS3824 family, easing layout reuse. The device monitors a single voltage and requires no external timing capacitor — the 120ms timeout is fixed internally, reducing BOM count and eliminating a potential tolerance drift path.

No stock-holding claim — each order is sourced per RFQ.

Frequently asked questions

Does TPS3824-50DBVT have active low or active high reset output?

Both. The TPS3824-50DBVT provides a push-pull output that can be configured for active-high or active-low assertion. Pin /RESET drives low on fault; pin RESET drives high on fault — two separate outputs on the same chip.

What is the closest functional second-source to TPS3824-50DBVT?

The TLV803EA29VDBZR is a similar simple reset supervisor from TI, but it differs in key parameters: its threshold is 2.93V (not 4.55V), its output is open-drain (not push-pull), and its timeout is 130ms minimum vs 120ms. The TLV803ED29DBZR has a 33ms timeout. Neither is a direct pin-for-pin replacement for the TPS3824-50DBVT — confirm your voltage threshold and output type before substituting.
