POWER MANAGEMENT PRODUCT BRIEF Neo-Iso™ Isolated Power FEATURES • Low quiescent operating current –– 2μA in OFF state –– 4μA in ON state • Scalable galvanic from primary to secondary sides of the device • Switch Turn-On / Turn-Off Times ~25μS • Single control signal for on/off input (CLK) • Operation from 2.7V to 5.5V compatible with standard microcontrollers • Low profile allows thin and compact end products • Silent operation improves user experience APPLICATIONS • Internet Of Things (IoT) • HVAC / Thermostats • Home Automation / Smart Home • Security • Smart Metering Neo-Iso™ Isolated Load Switches POWER MANAGEMENT SOLUTIONS Semtech Neo-Iso™ technology from Semtech enhances Internet of Things applications by adding higher levels of intelligence and control. Neo-Iso switches make it possible for low-power microcontrollers to control high voltage loads in the system. Reporting of fault conditions from the switch to the controller enables system responses resulting in safer, more efficient operation. Low current draw allows each switch to operate off of power harvested from the load, eliminating the need for additional supplies. Implemented in proven, volume manufacturing processes, consistently high levels of reliability are achieved throughout the entire operating life. Semiconductor-based design allows future scalability and integration options not possible with legacy technologies such as mechanical relays and opto-couplers. • Industrial Control C2 C1 (Internal) (Internal) VDD2 VDD1 Isolation Barrier GPIO1 CISO CLK Cdata DATA VCC GPIO2 µC SYSP VDD2 VDD1 SW1 Ccp VCC CPP Digital Control Ilimit Detect SUB Biasing SUB Csub Switch Driver TS13101 VAC Csys Load • Switch characteristics: –– 60V switch with bi-directional blocking in OFF state –– 110m ohm Rdson –– Up to 4A operating current SW2 SYSM SRC TS13101 Latching, Single Channel www.semtech.com 1 POWER MANAGEMENT PRODUCTS | PRODUCT BRIEF C2 C1 SYSTEM IMPLEMENTATION DIAGRAM WITH AC POWER HARVESTING VDD2 VDD1 SYSP CPP • IC power can be harvested either from CLK charge pump or from AC power harvesting Csys Ccp SW1 CLK DATA Digital Control Ilimit Detect SW2 SUB Biasing VCC • System pins can also be powered from an external power supply VAC Switch Driver Load • Control power is received from the Switch pins and stored on the System pins CISO Cdata SUB GPIO1 SRC Csub VCC SYSM GPIO2 C2 C1 uC VDD2 VDD1 SYSP CPP GPIO3 Ccp SW1 CLK Cdata DATA Digital Control Switch Driver Load CISO Ilimit Detect SW2 SUB Biasing SUB SRC Csub SYSM Clock LATCH ON/OFF SEQUENCING - TS13101 On Sequence On Sequence Switch State Off Sequence Latched ON Latch Mode On/Off Sequence • A unique digital pattern is used to turn on/off the solid-state switch. During the non-transition periods, the input can be clocked to power the device or not clocked and receive power from the solid state switch side.
