Analog Devices Inc./Maxim Integrated MAX16013TT

Overview

MAX16013TT from Maxim Integrated is an ultra-small, low-power overvoltage protection IC designed for high-voltage, high-transient systems. It drives two external p-channel MOSFETs (P1 and P2) to provide reverse-battery protection and programmable overvoltage switching or limiting, operates from 5.5V to 72V supply, features 2µs max propagation delay, and is rated for -40°C to +125°C operation in automotive and industrial power rails.

For engineers reviewing the MAX16013TT datasheet, MAX16013TT pinout, MAX16013TT application, or MAX16013TT equivalent, this page delivers verified functional role, real-world timing behavior, gate-drive voltage clamping characteristics, hysteresis options, and precise thermal and supply-current performance across temperature - all critical for robust 48V telecom, automotive load-dump, and multicell battery-stack protection designs.

Technical Context

The MAX16013TT integrates dual gate drivers (GATE1 and GATE2) with independent control logic: GATE1 enhances a p-channel MOSFET (P1) for reverse-battery protection with 10V V_GS clamp (11V ≤ V_CC ≤ 72V), while GATE2 controls P2 for overvoltage response. Its SET input accepts an external resistive divider to program overvoltage threshold with 0.5%/5%/7.5% hysteresis options.

During overvoltage events, GATE2 pulls to V_CC to turn off P2 (switch mode) or cycles P2 to regulate output voltage (limiter mode); GATE1 remains active unless V_CC drops below UVLO (4.75V–5.25V). The device includes internal undervoltage lockout and fast 2µs propagation delay for transient response.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power-management ICs for demanding industrial, automotive, and communications applications.

The MAX16010–MAX16014 family was engineered specifically for ultra-compact, high-voltage overvoltage and reverse-battery protection in space- and reliability-constrained systems such as automotive body electronics and 48V server power rails.

FAQ

What is the exact overvoltage threshold hysteresis setting for MAX16013TT?

The MAX16013TT uses a fixed 5.0% hysteresis setting, confirmed in the Electrical Characteristics table (hysteresis row, "MAX16010TAB/MAX16011TAB/MAX16013/MAX16014" column). This value defines the difference between rising (V_TH+) and falling (V_TH-) trip thresholds, ensuring stable switching without chatter during noisy voltage transitions. The hysteresis is factory-set and not user-adjustable on the MAX16013TT.

How does MAX16013TT handle reverse-battery conditions?

The MAX16013TT prevents reverse-battery damage by driving GATE1 to enhance P1 (external p-channel MOSFET) during normal operation, while actively pulling GATE1 to GND during reverse polarity. This reverse-biases P1's gate-source junction, turning it off completely and blocking current flow. No external diode is needed, reducing forward voltage drop to I_LOAD × R_DS-ON - typically millivolts - preserving system efficiency in battery-powered equipment.

Can MAX16013TT operate in overvoltage limiter mode, and what design considerations apply?

Yes, MAX16013TT supports overvoltage limiter mode by connecting the SET resistive divider to the P2 output (load side) instead of V_CC. In this configuration, GATE2 cycles P2 to regulate output voltage within ~5% of the programmed threshold. However, prolonged limiter operation causes high P2 power dissipation (P2 = (V_CC − V_OV-ADJUSTED) × I_LOAD), requiring careful MOSFET selection and heatsinking - unlike MAX16013TT's default switch-mode operation which dissipates negligible power.

What is the maximum recommended gate capacitance for external MOSFETs driven by MAX16013TT?

MAX16013TT's GATE1 and GATE2 outputs are rated to sink ≥75µA and source ≥1µA. While no explicit gate capacitance limit is specified, layout practice and typical 2µs propagation delay imply compatibility with p-MOSFETs having total gate charge (Q_g) ≤ 20nC - corresponding to ~10nF effective gate capacitance at 2V/ns slew rate. For higher Q_g devices, an external pullup resistor (e.g., 2MΩ from V_CC to GATE2) is recommended to ensure fast turn-on without compromising turn-off speed.

Does MAX16013TT require external pullup resistors on its gate-driver outputs?

External pullup resistors are optional but recommended for robustness: a 2MΩ resistor from V_CC to GATE2 improves turn-on speed during overvoltage recovery without degrading turn-off capability (75µA sink current limits minimum resistor to ~147kΩ). GATE1 similarly benefits from pullup in high-capacitance MOSFET applications. The resistor value balances power consumption (lower values increase quiescent current) and switching speed - 2MΩ is the documented value in Maxim's Typical Operating Circuit for MAX16013TT.
