E-L9826

STMicroelectronics · Power Distribution Switches · SOIC-20-300mil

E-L9826 from STMicroelectronics, in a SOIC-20-300mil. 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 Out 6 output Low-side driver output 6 with continuous output voltage limited to -0.7 V to 45 V and inductive turn-off clamping typically 50 V.
2 Out 1 output Low-side driver output 1, controllable by SPI or by parallel input NON1, with short-circuit current limitation and thermal shutdown.
3 NRes input Asynchronous active-low reset input with internal pull-down of 50 kOhm to 250 kOhm, which resets all registers and disables all outputs.
4 NCS input Active-low SPI chip select, with the device selected while low and the rising edge latching the shift register data to the outputs.
5 GND power_in Device ground.
6 GND power_in Device ground.
7 NON1 input Active-low parallel control input for output 1, internally pulled up so that output 1 is off when the input is open.
8 SDO tri_state Serial diagnostic data output that is tri-stated when NCS is high, with propagation delay from CLK to valid data of 100 ns maximum.
9 Out 8 output Low-side driver output 8 with overcurrent and short-circuit shutdown, output current limited to -2 A to 1.0 A.
10 Out 3 output Low-side driver output 3 with overcurrent and short-circuit shutdown, output current limited to -2 A to 1.0 A.
11 Out 5 output Low-side driver output 5 with overcurrent and short-circuit shutdown, output current limited to -2 A to 1.0 A.
12 Out 2 output Low-side driver output 2, controllable by SPI or by parallel input NON2, with short-circuit current limitation and thermal shutdown.
13 SDI input Serial data input receiving the 8-bit SPI command, sampled on each CLK falling edge.
14 CLK input Serial clock input with maximum frequency of 3 MHz at 50% duty cycle.
15 GND power_in Device ground.
16 GND power_in Device ground.
17 NON2 input Active-low parallel control input for output 2, internally pulled up so that output 2 is off when the input is open.
18 VCC power_in Supply voltage, specified for operation from 4.5 V to 5.5 V with absolute maximum of 7 V.
19 Out 7 output Low-side driver output 7 with overcurrent and short-circuit shutdown, output current limited to -2 A to 1.0 A.
20 Out 4 output Low-side driver output 4 with overcurrent and short-circuit shutdown, output current limited to -2 A to 1.0 A.
