Manufacturer:TI Description:The SN54LS93J has been designed with an internal over temperature protection circuit. The circuit provides a diagnostic in the event an over temperature condition occurs in the power stage. The circuit normally outputs a voltage level < 0.5Vdc. When the power stage reaches 140C, the VSN54LS93JUT (pin19) will rise to +15Vdc. The SN54LS93J also outputs a control function for this circuitry. A logic 0 at pin 18 will disable the over temperature circuit and a logic 1 will force VSN54LS93JUT to go high. The over temperature circuitry has been designed to interface with a system controller. The system controller can act on the pretense of an over temperature and shut the SN54LS93J down. The system controller may opt to over ride the over temperature flag and disable the circuit over temperature circuitry. In addition, the system controller can force the VSN54LS93JUT high as part of a built in test (BIT) feature at the system level. The over temperature circuitry will reset when the power stage has cooled to 130C. Finally, an internal diode can be jumpered causing the temperature circuitry to latch on trip, requiring a power off reset. |
