TPS389033GQDSERQ1

Texas Instruments · Supervisor And Reset ICs · WSON-6(1.5x1.5)

TPS389033GQDSERQ1 from Texas Instruments, in a WSON-6(1.5x1.5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SENSE input Voltage input to be monitored; RESET asserts when SENSE falls below negative threshold voltage VITN, and deasserts when SENSE rises above positive threshold voltage VITP.
2 GND power_in Ground connection.
3 MR input Manual reset input; driving MR low causes RESET to assert.
4 VDD power_in 3.3V supply voltage input; place 0.1-µF ceramic capacitor close to this pin for good analog design practice.
5 CT passive Capacitor connection for user-adjustable reset delay time; connect to ground-referenced capacitor to set RESET delay per tPD(r) = CCT × 1.07 + 25 µs.
6 RESET tri_state Open-drain reset output asserted low when either MR is low or SENSE is below VITN; remains low for delay period after both MR and SENSE return to valid levels; requires 10 kΩ to 1 MΩ pullup resistor.
