Product Description

PCLT-2AT4 new electronic ic chips Surge Suppressors Dual current limited over Vltg

Features

■ 2 channel topology: low side input with common ground

■ Wide range input DC voltage:

– VI = - 0.3 to 30 V with RI = 0 Ω – VI = - 30 to 35 V with RI = 750 Ω

■ Current limiter: – 3 to 7.5 mA programmable reference

– ILIM = 6.1 mA to 8.8 mA with RREF = 10 kΩ – ILIM = 2.8 mA to 4.3 mA with RREF = 22 kΩ

– Narrow limiter spread: < 17%

– Temperature compensated operation

■ Output drive:

– No output activation below 2 mA input

– 1.5 mA minimum output activating current in opto-coupler mode

– Programmable CMOS output mode option (VMOD > 2.9 V)
