TPS3840DL32DBVRQ1

Texas Instruments · Supervisor And Reset ICs · SOT-23-5

TPS3840DL32DBVRQ1 from Texas Instruments, in a SOT-23-5. 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 RESET output Open-drain, active-low reset output signal; driven low when VDD falls below VIT- (3.2 V) or MR pin is pulled to logic low (< 600 mV); maximum output current ±70 mA; absolute voltage rating -0.3 V to 12 V.
2 VDD power_in Input supply voltage monitored by internal comparator; operating range 1.5 V to 10 V; typical quiescent current 350 nA at 1.5 V < VDD < 10 V and VDD > VIT+; absolute maximum rating 12 V.
3 GND power_in Ground reference potential; 0 V reference for all circuit nodes.
4 MR input Manual reset input with internal 100 kΩ pull-up to VDD; pull below 600 mV (VMR_L) to assert reset; can be left floating when not used; accepts 0 V to VDD voltage; absolute maximum rating 12 V.
5 CT passive Capacitor time delay pin with internal resistance 350-650 kΩ for user-programmable reset delay ranging from 50 µs (no capacitor) to 6.2 s (10 µF); connect external capacitor to ground to set delay; absolute voltage rating -0.3 V to 5.5 V.
