MAX16016LTBS+T Présentation
A microprocessor supervisory circuit (also called a voltage supervisor, reset IC, or power monitor) is a dedicated IC that watches one or more system supply rails and asserts a reset signal whenever the rail falls outside a valid window. It sits between the power supply and the host MCU or CPU as part of the broader power management hierarchy (supervisor -> power monitor -> power management IC -> mixed-signal semiconductor), providing deterministic boot behavior, brownout protection, and orderly recovery from power-loss events that a generic voltage regulator cannot guarantee.
Key features include a single supervisor channel with push-pull, totem-pole reset output, an integrated battery-backup switchover path, chip-enable gating for SRAM/EPROM write protection, and a nominal supply monitor threshold of 1.62 V. The compact 10-pin TDFN package measures only 3 mm × 3 mm with a maximum seated height of 0.8 mm, making the part suitable for handheld, portable, and densely populated industrial boards where board area is at a premium.
Internally, the MAX16016 family uses a precision bandgap reference and comparator chain to detect undervoltage conditions, combined with a low-on-resistance MOSFET for transparent battery-backup switching. The chip-enable gating logic prevents spurious write cycles to external memory during power transitions, which is critical for deterministic firmware behavior in 1.8 V, 2.5 V, 3.0 V, 3.3 V, and 5 V logic systems. Compared with discrete reset solutions, the MAX16016 reduces external component count, simplifies PCB layout, and improves long-term reliability.
Typical applications include supervisory control in portable battery-backed equipment, point-of-sale terminals, industrial controllers, and any μP system that requires power-on reset (POR), brownout reset, battery switchover, and memory write protection. The part is particularly suited to designs that must retain SRAM contents through primary power loss.
When designing with the MAX16016LTBS+T, place the decoupling capacitor (per datasheet typical application) as close as possible to the VCC pin and verify the exposed pad is soldered to a sufficient copper pour for thermal and electrical performance. Carefully review the battery-backup current path and confirm the backup supply voltage is within the device's specified range to ensure proper switchover behavior.

Applications typiques
MAX16016LTBS+T convient pour 7 applications: Battery-Backed Portable Equipment, Point-of-Sale (POS) Terminals, Industrial Microprocessor Controllers, Embedded Memory Write Protection, Automotive Infotainment & Body Electronics, IoT Edge Devices & Sensor Hubs, Test & Measurement Instrumentation.
Battery-Backed Portable Equipment
The MAX16016LTBS+T is purpose-built for portable battery-backed systems where SRAM or configuration memory must survive primary power failure. The integrated battery-backup switchover redirects the load to a coin-cell or supercap when VCC drops below the reset threshold, preserving memory contents without external MOSFETs. The push-pull totem-pole reset drives the host MCU directly without external pull-up resistors, saving board space. With a 10-pin TDFN (3x3 mm) footprint and -40°C to +85°C industrial temperature range, the part fits handheld instruments, portable data loggers, and medical telemetry devices where reliable memory retention is non-negotiable.

Point-of-Sale (POS) Terminals
POS terminals rely on deterministic boot behavior and tamper-resistant memory to protect transaction logs. The MAX16016LTBS+T's chip-enable gating blocks spurious writes to external SRAM/flash during power glitches, while the integrated supervisor detects brownout conditions that could corrupt transaction records. The compact 10-pin TDFN package fits within the constrained PCB area of countertop terminals, and the industrial temperature grade supports kitchen and warehouse environments. Combined with battery backup for graceful shutdown during unexpected power loss, the part meets the reliability demands of retail and hospitality payment systems.

Industrial Microprocessor Controllers
Industrial controllers - sensor hubs, PLCs, and motor-control front-ends - require robust brownout protection and memory integrity during noisy supply transients. The MAX16016LTBS+T's 1.62 V nominal threshold suits modern 1.8 V logic cores, and the push-pull totem-pole reset output interfaces directly with μP reset pins without external components. The -40°C to +85°C industrial temperature grade supports factory-floor and outdoor cabinet installations. The exposed pad on the 10-pin TDFN package enhances thermal dissipation in enclosed IP65/IP67 enclosures where ambient temperatures may approach the upper operating limit.
Recommandé
Embedded Memory Write Protection
Systems with battery-backed SRAM, EPROM, or configuration EEPROM need write protection during power transitions to prevent corrupted data. The MAX16016LTBS+T's chip-enable gating output blocks CE pulses while VCC is outside the valid window, ensuring that no write cycles occur during power-up, power-down, or brownout recovery. This single-function integration replaces discrete gating logic that would otherwise require comparators and AND gates. The 10-pin TDFN package keeps the protection function on a small portion of the main board, ideal for data-acquisition modules and industrial gateways.
Recommandé
Automotive Infotainment & Body Electronics
In cabin-mounted automotive modules - infotainment head units, instrument clusters, and body controllers - the MAX16016LTBS+T provides deterministic reset behavior across cranking transients and accessory power events. The industrial temperature grade handles under-dash thermal conditions, and the supervisor's fast reset assertion prevents the host MCU from executing corrupted code during load-dump recovery. The small 10-pin TDFN footprint is advantageous for space-constrained PCBAs where multiple subsystems compete for board area, and battery backup supports key-off memory retention for user preferences and diagnostic logs.
Recommandé
IoT Edge Devices & Sensor Hubs
Battery-powered IoT edge nodes and sensor hubs require supervisor ICs that consume minimal quiescent current while still providing reliable reset behavior. The MAX16016LTBS+T's low-power design preserves battery life, and its battery-backup switchover maintains RTC and event-log integrity during primary cell replacement. The 10-pin TDFN (3x3 mm) package suits the smallest sensor packages, including wearable health monitors and wireless environmental sensors. Combined with chip-enable gating for external flash, the part prevents corrupted firmware writes during low-battery brownout events - a common failure mode in field-deployed IoT devices.
Recommandé
Test & Measurement Instrumentation
Bench-top and portable test instruments - multimeters, oscilloscopes, signal analyzers - require calibration data and measurement history to survive power cycling. The MAX16016LTBS+T's battery-backup switchover preserves SRAM contents storing last-measurement and user-setup data, while the supervisor ensures deterministic boot into known calibration tables. The industrial temperature grade supports lab and field environments, and the small TDFN-10 footprint allows integration into handheld DMMs and clamp meters where PCB area is severely limited. Chip-enable gating prevents configuration memory corruption during hot-swap battery events.

Notes de conception
Solder the exposed thermal pad of the 10-pin TDFN package to a sufficient copper pour on the PCB - typically at least 25 mm² of connected copper - to meet the thermal and electrical grounding requirements of the datasheet. Place the VCC decoupling capacitor (typically 0.1 µF ceramic) within 2 mm of the VCC pin and connect it directly to the ground plane. Route the RESET trace away from high-current switching nodes to prevent coupling of supply transients into the reset output.
When configuring battery backup, ensure the backup source (coin cell or supercap) stays within the BATT input voltage range specified in the datasheet and that the battery's reverse-leakage current is accounted for in the standby power budget. The MAX16016 automatically switches the VOUT load from VCC to BATT when VCC falls below the reset threshold - confirm that the backup battery voltage does NOT exceed the absolute maximum rating, especially during battery insertion transients.
Do not assume the MAX16016LTBS+T is interchangeable with the simpler MAX803 family - the MAX16016 is a 4-function supervisor (monitor + reset + battery backup + CE gating) in a 10-pin TDFN package, while MAX803-series parts are 3-pin SC70 single-voltage monitors. Also confirm the reset-threshold suffix (LTBS, LTBV, LTBW, LTBZ, LTBL) matches your supply rail voltage - substituting a different suffix will cause incorrect reset assertions at the wrong threshold and may prevent system startup.
The chip-enable gating output (CEOUT) must drive only one memory CE input - if multiple memory devices share the CE line, add external buffering. Verify the CEIN-to-CEOUT propagation delay is acceptable for your system's write-cycle timing - refer to the datasheet timing diagram. Keep the CE traces short and routed away from noisy power-switching signals to maintain signal integrity during high-impedance states.
