STP04CM05XTTR

STMicroelectronics · LED Drivers · HTSSOP-16-EP

STP04CM05XTTR from STMicroelectronics, in a HTSSOP-16-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 GND power_in Ground terminal; the datasheet rates the GND terminal current at 2000 mA absolute maximum.
2 GND power_in Ground terminal; the datasheet rates the GND terminal current at 2000 mA absolute maximum.
3 SDI input Serial data input terminal; logic high requires at least 0.7 VDD and logic low must stay at or below 0.3 VDD, with absolute input range -0.4 V to VDD+0.4 V.
4 CLK input Clock input terminal for the 4-bit serial-in shift register, rated up to 30 MHz in cascade operation.
5 LE input Latch input terminal; when high the latch refreshes its data from the SDI chain, and when low it holds the previous data set.
6 OUT 0 output Constant-current output channel 0, 80 to 400 mA per channel set by R-EXT, with 20 V output driving capability.
7 OUT 1 output Constant-current output channel 1, 80 to 400 mA per channel set by R-EXT, with 20 V output driving capability.
8 N.C. unconnected Not connected.
9 N.C. unconnected Not connected.
10 OUT 2 output Constant-current output channel 2, 80 to 400 mA per channel set by R-EXT, with 20 V output driving capability.
11 OUT 3 output Constant-current output channel 3, 80 to 400 mA per channel set by R-EXT, with 20 V output driving capability.
12 N.C. unconnected Not connected.
13 OE input Output enable input, active low; when high all outputs are switched off.
14 SDO output Serial data output terminal; with IOH = -1 mA the output is at least VDD-0.4 V high, and with IOL = 1 mA it is at most 0.4 V low.
15 R-EXT passive Constant-current programming terminal; an external resistor connected here sets the output current of OUT 0 to OUT 3.
16 VDD power_in 5 V supply voltage terminal; recommended range 3.3 V to 5.5 V (5.0 V typical), absolute maximum 0 to 7 V.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
