HV320 General Description
The Supertex HV320 re-settable electronic circuit breaker is designed to provide fast, consistent and accurate current limiting and load isolation during fault conditions. It may be used in a variety of applications in such markets as telecom, power, automotive, industrial, medical and security as well as in systems where active control is implemented in the negative supply lead. The current trip threshold is programmed by a sense resistor and operates from voltages ranging from 10V to 90V differentially.
The HV320 can easily replace popular positive temperature coefficient (PTC) products such as Raychem™ PolySwitches™ or re-settable polyfuses. HV320 overcomes numerous performance shortcomings of existing PTC’s, including trip point inaccuracy, increased device resistance after initial reset, slow response time, susceptibility to temperature variations and very high trip current to operating current.
During initial application of power, the gate of the external pass device is clamped low to suppress contact bounce glitches. Thereafter, the UV/OV supervisors and power-on reset work together to suppress gate turn on until the input
power bounce ends. Once ON, HV320 continues to monitor the input voltage and the load current level. If a load fault occurs, the electronic circuit breaker will trip and the pass element will be turned off. To restart, the UV or OV pins must be toggled (for example by resetting the input voltage).
HV320 Maximum Ratings
Vee referenced to Vin pin ..........+0.3V to -100V
VUV and VOV referenced to Vee Voltage ...-0.3V to +12V
Operating Ambient Temperature ...... -40 to +85
Operating Junction Temperature ......-40 to +125
Storage Temperature Range........ -65 to +150
*Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the devide at the absolute rating level may affect device reliability. All voltages are referenced to device ground.
