The reset output is active-low with a push-pull, totem-pole stage, so no external pull-up resistor is needed on the reset line to the processor. ## SOT-23-5 footprint and industrial temperature range Packaged in a SOT-23-5, the TPS3820-50DBVRG4 fits into tight board layouts where a supervisor is needed without consuming much real estate.","metaTitle":"TPS3820-50DBVRG4 Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3820-50DBVRG4 simple reset/power-on reset IC with active-low push-pull output, 4.55V threshold, 15ms timeout, SOT-23-5.
