What are the key features of MAX16128UAACAC+?
- Single-channel input fault protection controlling an external P-channel MOSFET to guard against load-dump pulses up to 40 V and reverse-polarity input events
- Automotive-grade design suitable for 12 V systems, with integrated charge pump for gate drive and accurate voltage threshold detection
- Compact 8-pin TSSOP (MINI_SO) package enables space-efficient placement near automotive ECU power input stages
What is MAX16128UAACAC+ used for?
The MAX16128UAACAC+ is primarily used in automotive ECU power input protection stages, where it controls a P-channel MOSFET to absorb ISO 7637 load-dump transients up to 40 V on a 12 V battery bus without damage to downstream regulators or microcontrollers. It is also deployed in industrial equipment connected to vehicle battery systems and fleet management telematics units, where reverse battery connection is a common field failure mode. The 8-pin TSSOP footprint makes it easy to integrate into existing power input filter stages on compact PCBs.

Frequently Asked Questions
What fault conditions does MAX16128UAACAC+ protect against and at what voltage levels?
The MAX16128UAACAC+ protects against load-dump transients up to 40 V and reverse-polarity battery connections on a 12 V automotive supply rail. It uses an external P-channel MOSFET as the series protection element, controlled by an integrated charge pump that provides proper gate drive across the input voltage range.
How does MAX16128UAACAC+ respond to an ISO 7637 load-dump event in an automotive ECU?
When a load-dump pulse raises the battery bus above the set threshold, MAX16128UAACAC+ drives the external P-channel MOSFET toward cutoff within microseconds, clamping the voltage presented to downstream circuitry. The response time is fast enough to meet ISO 7637 pulse profiles at repetition rates expected on 12 V automotive platforms, protecting regulators and microcontrollers rated below 40 V.
Which external component determines the protection MOSFET selection for MAX16128UAACAC+?
The user selects a P-channel MOSFET with a drain-to-source voltage rating of at least 40 V and a continuous drain current rating sufficient for the ECU's maximum load current, typically 1 A to 10 A depending on application. The MAX16128 charge pump supplies a gate voltage at least 5 V below the source to ensure the MOSFET stays fully on in normal operation with minimal RDS(on) power loss.
Why is the 8-pin TSSOP package of MAX16128UAACAC+ advantageous for automotive power input designs?
The 8-pin TSSOP (0.65 mm pitch) occupies roughly 19 mm² of PCB area, allowing the protection controller to be placed directly at the power input connector on space-constrained ECU boards. This eliminates the need for larger DIP or SOIC footprints and reduces input trace inductance, which can amplify transient voltages if the protection device is mounted far from the connector.
