Description
The integrated circuit ú1510 is used to switch
arbitrary loads on AC lines.
These loads may be inductivities, capacities or
resistances.
The circuit has a CMOS/TTL input with schmitt
trigger character.
Integrated functions protect the circuit versus short
circuit and overtemperature.

q Stand-by power dissipation < 0.02W
q Minimum external components
q ESD-protected input
q Integrated short circuit and overtemperature
protection
q Temperature range 0°C ... +70°C
q Package SOP12LP 1510BT
Applications
q General switching element for analog voltages
q Electronic switch for power supply engines,
relays, magnetic valves, etc.

General function and description
The ú1510 is an electronic switch for comm on applications on the 120V/230V main and allows to switch
inductive, capacitive and resistive loads. The switch disposes an CMOS / TTL input. The IC is protected
versus short circuit and overtemperature.
Two fundamental configurations of the switch are possible:
• A bi-directional switch without a bridge rectifier is realisable by a series connection of the two inte-
grated high voltage DMOS transistors.
• The parallel connection of the high voltage DMOS transistors allows an unidirectional application.
PIN function and description
VDS
The ú1510 is designed for a supply voltage of VDS = 10 ... 14V. This pin supplies the control circuit with
an internal oscillator.
GND
The ground pin supplies the control circuit.
IN
The input of the switch is designed for TTL and CMOS applications. This pin owns an internal pull up to
support a simple input circuit.
SW1
SW1 is the Drain of a high voltage DMOS – Transistor. The SW1 is dielectric isolated from the control
circuit
SW2
SW2 educates the common Source of 2 high voltage DMOS – Transistors. The SW2 is dielectric isolated
from the control circuit
SW3
SW3 is the Drain of a high voltage DMOS – Transistor. The SW3 is dielectric isolated from the control
circuit
