8-PIN PWM SWITCHER CONTROLLER IC WITH CURRENT LIMITING TYPICAL APPLICATION Figure 1 - Typical application of IRU DESCRIPTION The IRU IC provides a low cost switching controller with true short circuit protection all in a compact 8-pin surface mount package, providing a low cost switching solution for dual supply processor applications that re-. It is difficult to use a number of relays with transistors, so, relay driver IC ULNA can be used for availing more relays. We can use seven relays with relay driver circuit using ULN and the relay driver circuit using ULN enables to use eight relays. The TPLLoutput pins 16 to 10 are connected to relays RL1 to RL7 and J2-Output port pins 1 -7 (pin 8 is relay coil power sense). The TPLLCOM, pin 9, is connected to the relay supply on TB1. This pin connects to the cathodes of free wheeling diodes for each output. It provides a discharge path when the inductive load is turned off.

Pin 8 is the base of eighth transistor. Pin 9 is the emitter as well as ground of all transistors. Pin 10 is known as common pin i.e. node of common cathode which is used for the fly-back diodes. Pin 11 is the collector of eighth transistor. 8-CHANNEL RELAY DRIVER WITH INTEGRATED 5-V LDO AND BROWN-OUT DETECTION SLISD–JUNE –REVISED FEBRUARY The 5-V regulator is powered from V IN, and the regulated output is within 5 V ± 5% over the operating conditions. The open-drain power-on reset (RST) pin remains low until the regulator exceeds the set threshold, and the timer. 8-PIN PWM SWITCHER CONTROLLER IC WITH CURRENT LIMITING TYPICAL APPLICATION Figure 1 - Typical application of IRU DESCRIPTION The IRU IC provides a low cost switching controller with true short circuit protection all in a compact 8-pin surface mount package, providing a low cost switching solution for dual supply processor applications.
