Analog Devices Inc./Maxim Integrated MAX15007BATT/V+T

Overview

MAX15007BATT/V+T from Maxim Integrated is a 5V fixed-output, ultra-low quiescent-current linear regulator designed for automotive power rails and battery-backed systems. It operates from 4V to 40V input, delivers up to 50mA output current, consumes only 11µA typical ground current at no load, features an active-high enable (EN) input, and withstands 45V load dump-enabling reliable operation in cold-crank and transient-heavy vehicle environments.

For engineers reviewing the MAX15007BATT/V+T datasheet, MAX15007BATT/V+T pinout, MAX15007BATT/V+T application, or MAX15007BATT/V+T equivalent, key selection criteria include its -40°C to +125°C automotive qualification, 300mV dropout at 50mA, thermal shutdown at +165°C, stable operation with 2.2µF ceramic output capacitor, and compatibility with space-constrained PCB layouts using the 3mm × 3mm 6-pin TDFN-EP package.

Technical Context

The MAX15007BATT/V+T integrates a p-channel pass transistor to maintain ultra-low quiescent current across full load (93µA typ at 50mA), enabling always-on functionality in low-power automotive modules. Its internal 1.23V reference and error amplifier regulate output via feedback (FB) in adjustable variants-but this part uses fixed 5V output, eliminating external resistor networks.

Unlike the MAX15006 series, the MAX15007BATT/V+T includes an EN pin that accepts logic-level or direct VIN connection for on/off control, reducing supply current to 3µA in shutdown. The device's thermal protection engages at +165°C with 20°C hysteresis, and short-circuit current limit is guaranteed at 80–350mA.

Key Specifications

Pinout & Package

MAX15007BATT/V+T is housed in a thermally enhanced 6-pin TDFN-EP package (3mm × 3mm) with exposed pad (EP) internally connected to GND. The EP must be soldered to a PCB ground plane for optimal thermal performance and is not intended as a functional ground connection.

FAQ

What is the maximum input voltage the MAX15007BATT/V+T can withstand without damage?

The MAX15007BATT/V+T has an absolute maximum input voltage rating of +45V, allowing it to survive automotive load-dump transients defined by ISO 7637-2. Continuous operation is specified from 4V to 40V; operation above 40V is limited to transient events only and must remain within the 45V absolute maximum to prevent permanent damage. This rating is validated across the full -40°C to +125°C temperature range.

Does the MAX15007BATT/V+T require an external feedback resistor network to set its output voltage?

No, the MAX15007BATT/V+T does not require external feedback resistors because it is a fixed 5.0V output variant. Unlike the MAX15007C series, which uses the FB pin for adjustable outputs from 1.8V to 10V, the MAX15007BATT/V+T internally configures the error amplifier for 5V regulation. The FB pin is not connected and should remain unpopulated or floating in the schematic.

How does the enable (EN) pin function on the MAX15007BATT/V+T, and what happens when it is left unconnected?

The EN pin on the MAX15007BATT/V+T is active-high with internal 0.5µA pulldown current. When left unconnected, the internal pulldown pulls EN to GND, placing the device in 3µA shutdown mode. To enable regulation, EN must be driven above 1.4V (VIH). Connecting EN directly to VIN is a common implementation for always-on operation, while MCU GPIO control enables precise power sequencing in complex systems.

Can the MAX15007BATT/V+T deliver its full 50mA output current at +125°C ambient temperature?

Yes, the MAX15007BATT/V+T can deliver 50mA at +125°C ambient-but only with proper thermal design. In the 6-pin TDFN-EP package, maximum allowable power dissipation at +125°C is 595.8mW. For VIN = 26V and VOUT = 5V, this yields ~26mA continuous output before thermal limiting. To sustain 50mA at +125°C, VIN must be ≤17.2V (calculated via PD = (VIN − 5V) × 50mA ≤ 595.8mW), or PCB copper area must exceed the 1in² reference used in thermal characterization.

Is the MAX15007BATT/V+T RoHS-compliant and lead(Pb)-free?

Yes, the MAX15007BATT/V+T is RoHS-compliant and lead(Pb)-free, as indicated by the "+" suffix in its part number per Maxim's ordering conventions. The device meets EU RoHS Directive 2011/65/EU and is manufactured using green packaging processes. The TDFN-EP package uses matte tin lead finish and contains no intentionally added lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE).
