CJDR9111

Changjing · Brushed DC Motor Drivers · SOT-23-6L

CJDR9111 from Changjing, in a SOT-23-6L. 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 2 output H-bridge output 2; per Table 7-1 it is Hi-Z in Coast, high in Reverse (IN 1 = 0, IN 2 = 1), low in Forward and Brake.
2 GND power_in Device ground; connect to system ground.
3 OUT 1 output H-bridge output 1; per Table 7-1 it is Hi-Z in Coast, low in Reverse, high in Forward (IN 1 = 1, IN 2 = 0), and low in Brake.
4 VCC power_in Logic power supply; recommended operating range is 2.0 to 6.0 V, with absolute maximum of -0.3 to 7 V.
5 IN 1 input H-bridge control input 1; logic input voltage range is 0 to 7.0 V, with a 100 kΩ internal pull-down that defaults it to low.
6 IN 2 input H-bridge control input 2; logic input voltage range is 0 to 7.0 V, with a 100 kΩ internal pull-down that defaults it to low.
