The TVS is active at 19.5 V minimum. TVS is Vishay SMAJ18A, SMC package. Output protection is a fixed 68-µF capacitor and a parallel 0.1-µF capacitor located at the output terminals. A schottky diode on the output clamps negative going transitions. Diode MBRS330T3, 3 A, 100 V is placed on the output to restrict output transients to -0.7 V when the load is disconnected. 4.2 Enable Signal ENUV Slide switch to operate ENABLE signal. The Enable signal is externally pulled to VIN through a resistor divider to set the UV to 10 volts. A 0.1-µF capacitor is used to help de-bounce the Enable switch. 4.3 Enable Signal ENSD Slide switch to operate ENABLE signal. The Enable signal is externally pulled to GND to place the device in low current standby. A 0.1-µF capacitor is used to help de-bounce the Enable switch. 4.4 Indicator LEDS A 4.3-V zener is used to limit the voltage range on the LEDs. A bipolar signal transistor is used to turn on the LED while keeping the PG, FLT and FFLT signals less than 0.3 V active. External interface is 0 V to 4.3 V. Table 1.

Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
