Improves PLC system reliability :automatically detects short-circuit, open-circuit, brown-out, and overtemperature
With an adjustable operating frequency of 20 kHz to 250 kHz and a multi-function latch-off pin able to implement an overtemperature
shutdown circuit, the SOIC-16 packaged controller offers circuit designers a high degree of flexibility.
The device features extensive on-chip fault detection including detecting DIO driver short circuits longer than 650 osec, DO driver short circuits longer than 440 osec, reverse polarity protection, undervoltage detection, and thermal protection including overtemperature
warning and thermal shutdown.
The ATA6826 provides several protection features such as overtemperature
warning and shutdown, overload, overvoltage protection, and full protection against short circuits.
A number of safety features protect against circuit damage and improve test time, including programmable current limiting, auto test (LED open/short detection), overvoltage and undervoltage, overtemperature
and automatic flash timeout timer for thermal LED protection during flash.
Integrated protection against overvoltage, overcurrent and overtemperature
conditions help shield equipment and personnel against transient, internal surges and other voltage disruptions.
The devices help provide both overcurrent and overtemperature
protection for the battery pack PCMs (protection circuit modules) used in compact consumer devices such as smartphones, MP3/4 players and portable GPS units.
The ATA6620 provides several protection features such as overtemperature
shut-down, full protection against short circuits and high-voltage-bus-line protection up to 60 V.
UnderVoltage LockOut (UVLO), OverCurrent Protection (OCP), Internal OverTemperature
Protection (OTP) and Brownout protection circuits are also on-chip.
When installed on the primary side of the circuit, in proximity to potential heat-generating components such as magnetics, FETs, or power resistors, the LVB125 device can help protect against damage caused by both overcurrent and overtemperature
conditions with a single component.
The CM3132 and CM3121 integrate overcurrent protection, overtemperature
protection, and reverse current protection, as well as under voltage lockout.
The device includes Integrated Overtemperature
/ Overcurrent Protection, Under-Voltage Lockout, Power-OK, Low Battery Detection and has a sense input option.
