To connect the CYPD3177-24LQXQ (U1) to the USB-C 2.0 Receptacle (J1), you should wire the relevant pins together. Follow these connections:
  1. U1:VBUS_IN to J1:VBUS (all VBUS pins should be connected together).
  2. U1:GND to J1:GND (all GND pins should be connected together).
  3. U1:D+ to J1:D+ (connect both D+ pins of J1).
  4. U1:D- to J1:D- (connect both D- pins of J1).
  5. U1:CC1 to J1:CC1.
  6. U1:CC2 to J1:CC2.
Additionally, you have capacitors C1 and C2 for decoupling. Their connections are:
  1. C1:P1 to VBUS, C1:P2 to GND.
  2. C2:P1 to VBUS, C2:P2 to GND.
Remember to place the capacitors near the U1 IC for effective decoupling.

@copilot can you suggest load switch mosfet I could use for this project which has 20V 5A of max output?
2y

copilot

Sure! You can consider using the AO3401A as the load switch MOSFET in your project. The AO3401A is a P-Channel MOSFET with a maximum drain-source voltage (VDS) of 30V and a continuous drain current (ID) of 4.2A. This MOSFET is available in an SMD SOT-23 package which is relatively easy to work with.
However, since the AO3401A has a maximum drain current of 4.2A, it might get close to its limit if your load current reaches 5A. You can also consider using the AON7408, a P-Channel MOSFET with a maximum drain-source voltage (VDS) of 30V and a continuous drain current (ID) of 7.2A. This MOSFET is available in an SMD DFN3x3 package.
Remember to choose a suitable gate resistor and a pull-up resistor for the MOSFET's gate to ensure proper turn-on/turn-off. And make sure to properly connect the MOSFET to the circuit following the desired high-side or low-side configuration, depending on your project needs.

puedes crear un circuito que combine el astable con el monoestable

@copilot puedes crear un circuito que combine el astable con el monoestable
1y

Claro, combinar un circuito astable con uno monoestable es una tarea común en el diseño de circuitos para lograr funcionalidades específicas, como la generación de pulsos de timing variados. Un circuito astable oscila continuamente entre dos estados, generando una onda cuadrada sin necesidad de un pulso externo, mientras que un circuito monoestable requiere un pulso de disparo para cambiar de estado y volverá a su estado original después de un periodo de tiempo determinado.
Para construir un circuito que combine ambos, podemos usar el temporizador 555 en dos secciones diferentes del circuito: una sección configurada en modo astable para generar una onda cuadrada continua, y otra sección configurada en modo monoestable para generar un pulso único cada vez que se dispara.
Circuito combinado Astable-Monoestable con 555 Componentes Requeridos:
  • 2x Temporizadores 555 (U3 para astable, U4 para monoestable)
  • Resistencias: R3, R4, R5 (valores a determinar según los tiempos deseados)
  • Capacitores: C3 (para el astable), C4 (para el monoestable)
  • 1x Botón de disparo para el monoestable (SW1)
Conexiones:
Sección Astable (U3):
  1. Conecte R3 entre VCC y U3:7 (PIN DISCHARGE).
  2. Conecte R4 entre U3:7 (PIN DISCHARGE) y U3:6 (PIN THRESHOLD).
  3. Conecte R4 también a U3:2 (PIN TRIGGER).
  4. Conecte C3 entre U3:6 (PIN THRESHOLD/TRIGGER) y GND.
  5. Conecte U3:4 (PIN RESET) a VCC para evitar el reinicio.
  6. Conecte la salida U3:3 (PIN OUT) a un LED (opcional) para visualizar la oscilación.
Sección Monoestable (U4):
  1. Conecte R5 entre VCC y U4:7 (PIN DISCHARGE).
  2. Conecte C4 entre U4:2 (PIN TRIGGER) y GND.
  3. Conecte el botón SW1 entre U4:2 (PIN TRIGGER) y VCC para el disparo.
  4. Conecte U4:4 (PIN RESET) a VCC para evitar el reinicio.
  5. La salida U4:3 (PIN OUT) será donde obtenemos el pulso del monoestable.
Funcionamiento:
  • Astable (U3): Oscilará continuamente generando una señal de onda cuadrada en la salida U3:3.
  • Monoestable (U4): Esperará un pulso de disparo por SW1, tras el cual generará un pulso único de duración determinada por R5 y C4, visible en la salida U4:3.
Vínculo de ambos cicuitos:
Si desea vincular el funcionamiento de ambos, por ejemplo, usar la salida del astable como disparador del monoestable, puede conectar una salida adicional de U3 (por ejemplo, mediante un buffer o directamente si los niveles de corriente lo permiten) al SW1 del monoestable, recordando que SW1 debería ser reemplazado por un circuito equivalente que actúe al cambio de estado de U3:3.
Consideraciones de diseño:
  • Cálculo de Componentes: Para calcular los valores de R3, R4, R5, C3, y C4, se debe tener en cuenta la fórmula para el cálculo del tiempo de oscilación y pulso para cada modo del 555. Asumiendo configuraciones típicas, para el astable $T = 0.693 \cdot (R3 + 2R4) \cdot C3$ y para el monoestable $T = 1.1 \cdot R5 \cdot C4$.
  • Ajuste según necesidad: Puede ajustar R3, R4, R5, y los valores de los capacitores para cambiar la frecuencia de la señal astable y la duración del pulso monoestable según requiera su aplicación específica.
Esta es una propuesta básica de integración de un circuito astable y uno monoestable utilizando temporizadores 555, recuerde que los valores específicos de los componentes dependerán de los requisitos de su aplicación.
