al check on a vehicle's primary airbag inflator verifies proper characteristics in the pyrotechnic initiator, a fusible wire with a typical resistance of about 2-3 ohms. a second test checks the safety shorting clip to verify that initiator pins are shorted together, a safety feature that prevents accidental activation during airbag handling and installation. the shorting clip is removed after installation is complete. a third test is a high voltage isolation resistance measurement to ensure that no el
e programmed via a dedicated serial interface port. the tlc5951 has three error detection circuits for led open detection (lod), led short detection (lsd), and thermal error flag (tef). lod detects a broken or disconnected led while lsd detects a shorted led. tef indicates an over-temperature condition. 2、tps61500 说明:the tps61500 is a monolithic switching regulator with integrated 3-a, 40-v power switch. it is an ideal driver for high brightness 1-w or 3-w led. the device has a wide input volt
