MAX16171 Ideal Diode Controller with Reverse-Current Protection General Description Benefits and Features The MAX16171 is an ideal diode controller that protects -42V to +76V Protection Range the load against damaging automotive transients down to Relaxes TVS Diodes Requirements -42V and blocks reverse-current flow within 600ns. The 4V to 57V Operating Range MAX16171 operates over a wide supply voltage range of Accommodates Wide Automotive Supply Rails 4V to 57V and withstands input transients up to 76V. In 9V Gate Drive Voltage with Respect to SRC light load applications, the device regulates the voltage Reduces MOSFET Power Dissipation drop across the external MOSFET to 20mV, allowing smooth, ring-free operation. At heavy load, the charge Enable Input pump drives the gate of the external MOSFET into an en- Provides On-the-Fly System Control hanced mode of operation and significantly improves ef- 1A Shutdown Current ficiency and power dissipation compared to traditionally Extends Battery Life used Schottky diodes. 600ns Reverse-Current Blocking Time with 10mV The MAX16171 consumes only 1A of current during Overdrive shutdown mode (V = GND) to extend battery life while EN Extends System Operation Time During Power providing standby power to the load through the body Interruption diode of the external MOSFET. An internal 2.5M resistor -40C to +125C Automotive Temperature Range between GATE and SRC keeps the external MOSFET off 2mm x 3mm, Side-Wettable TDFN Package when the input voltage drops below ground. The MAX16171 is available in a tiny 2mm x 3mm x Ordering Information appears at end of data sheet. 0.75mm, 8-pin TDFN package with side-wettable flanks and operates over the -40C to +125C automotive tem- Typical Application Circuit perature range. nFET Applications V V IN OUT Automotive Power Systems 100F Network Telecom Power Systems Redundant Power Supplies SRC GATE RAID Systems IN Servers MAX16171 0.1F OUT EN GND 19-100854 Rev 2 5/21MAX16171 Ideal Diode Controller with Reverse-Current Protection TABLE OF CONTENTS General Description 1 Applications 1 Benefits and Features 1 Typical Application Circuit . 1 Absolute Maximum Ratings 4 Package Information . 4 8 TDFN-CU . 4 Electrical Characteristics . 4 Typical Operating Characteristics 6 Pin Configuration 7 Pin Descriptions 8 Functional Diagram 8 Block Diagram . 8 Detailed Description . 9 Input Voltage Range . 9 Ideal Diode Reverse-Current Protection . 9 Charge Pump 9 EN Input 9 Reverse-Voltage Protection 10 Applications Information . 11 MOSFET Selection . 11 MOSFET Power Dissipation 11 Extended Protection . 11 Redundant Power Supplies 11 Layout Recommendations . 12 Typical Application Circuit 13 Typical Operating Circuit 13 Ordering Information 13 Revision History . 14 www.maximintegrated.com Maxim Integrated 2
