STMicroelectronics STEC01
The STEC01 is an integrated programmable 12 mΩ power switch managed by the timer based circuitry. The device has 3 timers designed to interrupt the ground path of a power application after a maximum on-time and inhibits the restart of the platform during a cooling window. The maximum on-time can be set from few seconds to hundreds of seconds, while the cooling window can be programmed to 69, 345 and 1380 seconds.| Part No. | STEC01 |

DESCRIPTION
3 multi-level input pins, combined with a programmable oscillator and a fixed oscillator, are used to set the timing. An input continuous or pulsed signal applied to the PWM pin starts the internal logic and counters. In case of a normal operation, as soon as the activity on the PWM pin stops, the device automatically enters idle mode, waiting for a new valid PWM signal to be applied. If the device detects a fault condition, a reset pulse is generated and the safety MOSFET is turned off and managed according to a predefined state machine.
