E-L9826TR

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

E-L9826TR 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	Output 6 of the octal low-side driver with 450 mA output current capability and overcurrent/short circuit shutdown.
2	Out 1	output	Output 1 with parallel control via NON1, 450 mA capability, short circuit limitation, and thermal shutdown (TJSC = 150-165 °C).
3	NRes	input	Asynchronous reset input (active low); resets all registers and disables all outputs when pulled low; internal pull-down 50-250 kΩ.
4	NCS	input	Chip select (active low) for SPI communication; internal pull-up 50-250 kΩ.
5	GND	power_in	Device ground reference.
6	GND	power_in	Device ground reference.
7	NON1	input	Parallel control input 1 (active low) for independent PWM control of Output 1; internal pull-up 50-250 kΩ.
8	SDO	tri_state	Serial data output for SPI diagnostic readout; tri-state (disabled when NCS high with leakage ±10 µA); max frequency 3 MHz.
9	Out 8	output	Output 8 with 450 mA capability and overcurrent/short circuit shutdown (ISBC = 0.45-1.1 A).
10	Out 3	output	Output 3 with 450 mA capability and overcurrent/short circuit shutdown (ISBC = 0.45-1.1 A).
11	Out 5	output	Output 5 with 450 mA capability and overcurrent/short circuit shutdown (ISBC = 0.45-1.1 A).
12	Out 2	output	Output 2 with parallel control via NON2, 450 mA capability, short circuit limitation, and thermal shutdown (TJSC = 150-165 °C).
13	SDI	input	Serial data input for SPI communication; 8-bit commands latched on CLK falling edge with setup time 20 ns and hold time 20 ns.
14	CLK	input	Serial clock input for SPI; maximum frequency 3 MHz; minimum low/high time 160 ns with 50% duty cycle.
15	GND	power_in	Device ground reference.
16	GND	power_in	Device ground reference.
17	NON2	input	Parallel control input 2 (active low) for independent PWM control of Output 2; internal pull-up 50-250 kΩ.
18	VCC	power_in	Positive supply voltage; operating range 4.5-5.5 V; absolute maximum rating 7 V.
19	Out 7	output	Output 7 with 450 mA capability and overcurrent/short circuit shutdown (ISBC = 0.45-1.1 A).
20	Out 4	output	Output 4 with 450 mA capability and overcurrent/short circuit shutdown (ISBC = 0.45-1.1 A).
