3 Description
The TPSI3052 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
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 can optionally supply power to external
supporting circuitry for various application needs.
The TPSI3052 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 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 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 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.
