3 Description

The TPSI3052-Q1 is a fully integrated, isolated switch

driver, which when combined with an external power

switch, forms a complete isolated Solid State Relay

(SSR). With a nominal gate drive voltage of 15 V

with 1.5/3.0-A peak source and sink current, a large

variety of external power switches can be chosen to

meet a wide range of applications. The TPSI3052-Q1

generates its own secondary bias supply from the

power received from its primary side, so no isolated

secondary supply bias is required. Additionally, the

TPSI3052-Q1 can optionally supply power to external

supporting circuitry for various application needs.

The TPSI3052-Q1 supports two modes of operation

based on the number of input pins required. In

two-wire mode, typically found in driving mechanical

relays, controlling the switch requires only two pins

and supports a wide voltage range of operation of 6.5

V to 48 V. In three-wire mode, the primary supply of

3 V to 5.5 V is supplied externally, and the switch

is controlled through a separate enable. Available in

three-wire mode only, the TPSI3052S-Q1 features a

one-shot enable for the switch control. This feature is

useful for driving SCRs that typically require only one

pulse of current to trigger.

The secondary side provides a regulated, floating

supply rail of 15 V for driving a large variety

of power switches with no need for a secondary

bias supply. The application can drive single power

switches for DC applications or dual back-to-back

power switches for AC applications, as well as various

types of SCR. The TPSI3052-Q1 integrated isolation

protection is extremely robust with much higher

reliability, lower power consumption, and increased

temperature ranges than traditional mechanical relays

and optocouplers.

The power transfer of the TPSI3052-Q1 can be

adjusted by selecting one of seven power level

settings using an external resistor from the PXFR pin

to VSSP. This action allows for tradeoffs in power

dissipation versus power provided on the secondary

depending on the needs of the application.
