Product details

Overview

MIC2827-B2YMT-TR from Micrel is a triple-output programmable power management IC (PMIC) integrating one 500mA synchronous buck regulator with HyperLight Load™ architecture and two 150mA low-dropout regulators (LDOs), all controlled via a 400kHz Fast-mode I²C interface. It delivers dynamic voltage scaling (DVS), power sequencing, and individual output enable/disable for mobile application processors, GPS subsystems, and portable media players.

For engineers reviewing the MIC2827-B2YMT-TR datasheet, MIC2827-B2YMT-TR pinout, MIC2827-B2YMT-TR application, or MIC2827-B2YMT-TR equivalent, key selection criteria include its 2.7–5.5V input range, 25µA quiescent current in HyperLight Load™ mode, ±3% output voltage accuracy over temperature, 14-pin 2.5mm × 2.5mm Thin MLF® package, and fault-aware IRQb interrupt signaling.

Technical Context

The MIC2827-B2YMT-TR implements a proprietary HyperLight Load™ architecture enabling ultra-low 25µA quiescent current while maintaining 90% peak efficiency and fast transient response across 0–500mA load range. Its 4MHz switching frequency minimizes external component size, and integrated DVS supports fine-grained voltage control: 0.8–1.2V in 25mV steps and 1.2–1.8V in 50mV steps for the buck, plus 0.8–3.3V in 50mV steps per LDO.

Power sequencing is hardware-enabled via the EN pin (default startup sequence DC→LDO1→LDO2) and software-configurable via I²C registers (00h–04h), with fault handling including thermal shutdown (160°C), UVLO (2.55V threshold), and Power-On-After-Fault (POAF) recovery logic. The IRQb open-drain flag signals active TSD or UVLO faults to host processors.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PMIC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS65023BRSBT	Triple-output PMIC with 600mA buck + two 200mA LDOs; 2.7–5.5V input; I²C interface; no HyperLight Load™ mode (quiescent current 50µA).	Higher LDO current capacity but lower light-load efficiency; lacks fast transient response optimization for burst-mode workloads.	Select when higher LDO output current (>150mA) is required and 25µA quiescent current is not critical.
MAX8649ETE+	Dual-output PMIC (500mA buck + 300mA LDO); 2.5–5.5V input; I²C interface; 30µA quiescent current; no integrated sequencing logic.	Missing third output and hardware-enforced power sequencing; requires external GPIO or firmware coordination for multi-rail startup.	Select when only two regulated rails are needed and software-controlled sequencing is acceptable.

Compared with TPS65023BRSBT and MAX8649ETE+, the MIC2827-B2YMT-TR uniquely combines triple-output capability, hardware sequencing, sub-30µA quiescent current, and 4MHz switching in a 2.5mm × 2.5mm footprint - making it optimal for space-constrained, battery-sensitive mobile platforms demanding coordinated multi-rail power delivery.

FAQ

What is the default startup voltage configuration for MIC2827-B2YMT-TR?

The MIC2827-B2YMT-TR has factory-programmed default startup voltages of 1.8V for the buck regulator, 1.2V for LDO1, and 2.8V for LDO2. These values are loaded into the respective voltage control registers (02h–04h) during power-on reset and can be modified via I²C writes at any time. The device also implements a default startup sequence of DC→LDO1→LDO2 when the EN pin is asserted.

Does MIC2827-B2YMT-TR support dynamic voltage scaling for all three outputs?

Yes, MIC2827-B2YMT-TR supports dynamic voltage scaling for all three outputs via its I²C interface. The buck regulator supports DVS from 0.8V to 1.8V (25mV steps below 1.2V, 50mV steps above), while each LDO supports DVS from 0.8V to 3.3V in 50mV increments. Voltage changes occur immediately upon I²C register write acknowledgment, enabling real-time adaptation to processor workload demands.

How does the IRQb pin function in MIC2827-B2YMT-TR during fault conditions?

The IRQb pin in MIC2827-B2YMT-TR is an open-drain fault indicator that asserts low when either thermal shutdown (TSD) or under-voltage lockout (UVLO) occurs. Its behavior is controlled by the INT-EN bit (D6) in the Status Register (01h). When enabled, IRQb remains low until both the fault condition clears and the corresponding status bit is echo-reset via I²C - ensuring reliable host processor notification without spurious interrupts.

What is the maximum junction temperature rating for MIC2827-B2YMT-TR?

The MIC2827-B2YMT-TR has a specified junction temperature operating range of –40°C to +125°C, with thermal shutdown activating at 160°C and hysteresis of 20°C. This allows safe operation in extended-temperature environments such as automotive infotainment systems and industrial handheld terminals, provided PCB thermal design meets the 89°C/W θ_JA specification for the 2.5mm × 2.5mm Thin MLF® package.

Can MIC2827-B2YMT-TR operate without using the I²C interface?

Yes, MIC2827-B2YMT-TR can operate fully without I²C communication by using the EN pin for default startup and shutdown. Asserting EN high initiates the factory-programmed voltage setpoints and sequencing (DC→LDO1→LDO2); toggling EN low shuts down all outputs simultaneously. I²C is optional and used only for advanced features like dynamic voltage scaling, individual rail control, fault status reading, and custom sequencing - not required for basic functionality.
