9 / 19 page TRIUNE SYSTEMS PROPRIETARY & CONFIDENTIAL INFORMATION - 9 - TS30021/22/23 Version 1.5 Specifications subject to change WWW.TRIUNESYSTEMS.COM Copyright © 2013, Triune Systems, LLC Under extended over current conditions (such as a short), the device will automatically disable. Once the over current condition is removed, the device returns to normal operation automatically. (Alternately the factory can configure the device’s NVM to shutdown the regulator if an extended over current event is detected and require a toggle of the Enable pin to return the device to normal operation.) Thermal Shutdown If the temperature of the die exceeds 170°C (typical), the VSW outputs will tri-state to protect the device from damage. The PG and all other protection circuitry will stay active to inform the system of the failure mode. Once the device cools to 160°C (typical), the device will start up again, following the normal soft start sequence. If the device reaches 170°C, the shutdown/restart sequence will repeat. SMPS Reference Soft Start The reference in this device is ramped at a rate of 4ms to prevent the output from overshoot during startup. This ramp restarts whenever there is a rising edge sensed on the Enable pin. This occurs in both the fixed and adjustable versions. During the soft start ramp, current limit is still active, and will still protect the device in case of a short on the output. SMPS Output Overvoltage If the output of the regulator exceeds 103% of the regulation voltage, the VSW outputs will tri-state to protect the device from damage. This check occurs at the start of each switching cycle. If it occurs during the middle of a cycle, the switching for that cycle will complete, and the VSW outputs will tri-state at the beginning of the next cycle. VCC Under-Voltage Lockout The device is held in the off state until VCC reaches 5.75V (typical). There is a 500mV hysteresis on this input, which requires the input to fall below 5.25V (typical) before the device will disable. LDO Internal Current Limit The LDO output current is sensed and if current limit is reached, it will restrict further current draw from the LDO. Current limit is always active when the regulator is enabled. |
