STMicroelectronics · Power Distribution Switches · HTSSOP-20-EP

IPS4260LTR from STMicroelectronics, in a HTSSOP-20-EP. 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 PGND power_in Integrated power switch ground; internally connected to source of integrated switches (pins 1, 2, 19, 20).
2 PGND power_in Integrated power switch ground; internally connected to source of integrated switches (pins 1, 2, 19, 20).
3 VZ output Load clamp voltage pin; must be shorted to pin 18 and connected to supply rail or external Zener/TVS diode for overvoltage clamping (55 V max).
4 IN1 tri_state Channel 1 logic input with open drain cut-off/thermal shutdown diagnostic; VIL 0.8 V, VIH 2.0 V, VIN max 5.5 V.
5 IN2 tri_state Channel 2 logic input with open drain cut-off/thermal shutdown diagnostic; VIL 0.8 V, VIH 2.0 V, VIN max 5.5 V.
6 IN3 tri_state Channel 3 logic input with open drain cut-off/thermal shutdown diagnostic; VIL 0.8 V, VIH 2.0 V, VIN max 5.5 V.
7 IN4 tri_state Channel 4 logic input with open drain cut-off/thermal shutdown diagnostic; VIL 0.8 V, VIH 2.0 V, VIN max 5.5 V.
8 SGND power_in Logic interface block ground with exposed pad; must be shorted to PGND on application board to minimize switching noise.
9 OL tri_state Open drain common diagnostic output for open load detection; active low when enabled with external pull-down resistor (VOL 0.1 V @ 5 mA).
10 FLT tri_state Open drain common diagnostic output for thermal shutdown and cut-off protection; active low during fault (VFAULT 0.1 V @ 5 mA).
11 CoD input Cut-off delay programming input; connect 60-240 kΩ resistor to SGND to set delay or short to SGND to disable cut-off protection (VCOD max 5.5 V).
12 ILIM input Current limit threshold programming input; connect resistor to SGND per formula ILIM = 60/RILIM[kΩ] for 30-120 kΩ range (VILIM max 5.5 V).
13 VCC power_in Supply voltage input; 8-50 V recommended operating range, 55 V absolute maximum.
14 LOAD4 output Channel 4 low-side power switch output for load connection to supply rail; integrates catch diode and thermal/current limiting protection (55 V max).
15 LOAD3 output Channel 3 low-side power switch output for load connection to supply rail; integrates catch diode and thermal/current limiting protection (55 V max).
16 LOAD2 output Channel 2 low-side power switch output for load connection to supply rail; integrates catch diode and thermal/current limiting protection (55 V max).
17 LOAD1 output Channel 1 low-side power switch output for load connection to supply rail; integrates catch diode and thermal/current limiting protection (55 V max).
18 VZ output Load clamp voltage pin; must be shorted to pin 3 and connected to supply rail or external Zener/TVS diode for overvoltage clamping (55 V max).
19 PGND power_in Integrated power switch ground; internally connected to source of integrated switches (pins 1, 2, 19, 20).
20 PGND power_in Integrated power switch ground; internally connected to source of integrated switches (pins 1, 2, 19, 20).
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
