Title:
【発明の名称】埋め込み型サーマルターンオフを有するイネーブル回路
Document Type and Number:
Japanese Patent JP3081228
Kind Code:
B2
Abstract:
An enable circuit that integrates thermal shutdown capability. The enable circuit utilizes a temperature insensitive threshold detector network that provides a desired biasing current when the ON/OFF signal applied at its input exceeds a preselected voltage. Thermally sensitive circuitry connected between the input of the threshold detector network and ground remains off when the ON/OFF signal is equal to the preselected voltage and the temperature of the enable circuit is below a preselected maximum temperature. However, when the temperature of the enable circuit reaches the preselected maximum temperature, the thermally sensitive circuitry turns on, clamping the input signal to the threshold detector network below the preselected voltage.
