That window gives the downstream MCU, FPGA, or SoC time to complete its internal power-on reset sequence before the reset pin releases. If your processor needs a longer hold time, you add an external capacitor to the MR pin on the TPS382x family — but the 120 ms minimum covers most 32-bit ARM and RISC-V cores out of the box. ## Push-pull output — no pull-up resistor needed The output is push-pull, totem pole, active low. That means the reset pin is driven both high and low — you do not need an external pull-up resistor to VDD. The output sinks or sources enough current to drive the reset input of most logic families directly. If your design uses an open-drain reset from another supervisor, this part is a drop-in replacement as long as the host reset input is active low. ## SOT-23-5 footprint — board area and layout Housed in a SOT-23-5 package (SC-74A, SOT-753), the part occupies about 3 mm × 3 mm of board area. The 0.95 mm pin pitch is wide enough for a two-layer PCB with basic routing. The small footprint makes it suitable for space-constrained designs like sensor modules, portable instruments, and industrial control I/O cards. ## Active lifecycle — no LTB surprise","metaTitle":"TPS3823-33DBVR Simple Reset IC, 2.93V Threshold, Active Low","metaDescription":"Texas Instruments TPS3823-33DBVR Simple Reset/Power-On Reset IC. 2.93V threshold, active low push-pull output, 120ms min timeout.
