SGM6602
Dual 2A load switch with independent control and ultra-low 0.5μA quiescent current for power gating applications
Product Overview
Description
The SGM6602 is a dual-channel load switch providing independent control of two power rails in a compact package.
Each channel supports up to 2A with 60mΩ on-resistance and ultra-low 0.5μA quiescent current when off.
The controlled slew rate and comprehensive protection features make it ideal for power gating in battery-powered systems.

FAE Expert Insights
"The SGM6602 is perfect for applications requiring independent control of multiple power rails. The dual-channel configuration saves significant PCB space compared to using two single-channel switches. I have used this part in wearable devices where space is at a premium and multiple sensors need independent power control. The 0.5μA off-state current is critical for maximizing battery life in sleep modes. The controlled slew rate prevents inrush current issues when switching capacitive loads. One consideration: the WLCSP package requires careful PCB layout and assembly, but the space savings are worth it for compact designs. For multi-rail power gating applications, this dual switch is an excellent choice."

Frequently Asked Questions
Can both channels of SGM6602 be used independently?
Yes, the SGM6602 features two completely independent channels with separate enable pins. Each channel can be turned on or off independently, allowing flexible power sequencing and power gating for multiple rails. Both channels share the same input voltage but have independent output connections.
Use independent enable pins to control each channel separately for flexible power management.
