IntersilThe HK7027A-1 is a RoHS-compliant microprocessor and microcontroller supervisors manufactured by HK Intersil. It is housed in an SOT-89-3 package and is designed to provide reliable reset functionality from a single supply voltage. It includes a supervisor IC and an MOSFET controlled reset output, improving system reliability by providing an active-high reset signal in response to a low power supply voltage. It is ideal for applications such as mobile and wireless systems, synchronous CPUs, programmable logic controllers, and embedded controllers. The device also features an under-voltage lockout and programmable reset timeout circuitry. The HK7027A-1 offers low operating voltage of 1.7V to 5.5V and reset threshold voltage of 1.5V to 4.4V. Additionally, the superior noise immunity and filter clock conditioning ensures reliable system performances.
