Product details
Overview
HPA00210DGSR from Texas Instruments is a regulated 3.3-V step-up charge pump IC designed for ultra-low-power battery-powered systems. It operates from 1.6 V to 3.6 V input, delivers ≥100 mA continuous output current at 2 V input, achieves <5 mVPP output ripple via push-pull topology, and features integrated low-battery detection (LBI/LBO) - used in glucose meters, MSP430-based portable instruments, and MP3 players.
For engineers reviewing the HPA00210DGSR datasheet, HPA00210DGSR pinout, HPA00210DGSR application, or HPA00210DGSR equivalent, key selection criteria include its 2 µA snooze-mode quiescent current, 90% peak efficiency, 10-pin MSOP (DGS) package with no inductor requirement, and compatibility with single-coin-cell or dual-alkaline battery inputs.
Technical Context
The HPA00210DGSR implements a dual-stage push-pull charge pump architecture with 180° phase-shifted flying capacitors (C1/C2), enabling continuous charge transfer to minimize output voltage ripple. Its regulation uses linskip mode - seamlessly switching between constant-frequency linear-regulation (>7 mA load) and pulse-skip mode (<7 mA) - controlled by internal error amplifier and MOSFET rDS(on) modulation.
Three operating modes are selected via the SNOOZE pin: low-power snooze (2 µA IQ, 3.3 V ±6%, 2 mA max load), normal operation (internal 200–400 kHz oscillator), or external clock synchronization (400–800 kHz). The LBI/LBO comparator provides user-configurable low-battery warning with 1.18 V ±5% trip threshold and 10 mV hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±4% (regulated over 1.6–3.6 V input and 0–100 mA load), ensuring stable MCU core supply under varying battery discharge. |
| Input Voltage Range | 1.6 V to 3.6 V - supports full discharge of two NiMH/alkaline cells or one Li-MnO₂ coin cell without brownout. |
| Max Continuous Output Current | 100 mA at VIN = 2 V - sufficient to power MSP430 microcontrollers, LCD backlights, and analog front-ends simultaneously. |
| Output Ripple | <5 mVPP at full load - achieved via push-pull topology and eliminates need for post-regulation LDO in noise-sensitive signal chains. |
| Quiescent Current | 35 µA typical (no load), 2 µA in snooze mode - lower than typical alkaline/NiMH self-discharge, extending shelf life of medical devices. |
| Switching Frequency | 200–400 kHz (internal), or synchronized to 400–800 kHz external clock - avoids IF band interference and enables EMI-controlled layout. |
| Low-Battery Detection | LBI input with 1.18 V ±5% threshold; open-drain LBO output - allows programmable battery cutoff using external resistor divider (R1/R2). |
Pinout & Package
HPA00210DGSR is housed in a 10-pin MSOP (DGS) package - 3.0 mm × 3.0 mm × 1.0 mm, thermally enhanced with exposed pad (not electrically connected). Pin numbering follows standard DGS outline with pin 1 at top-left corner when marking dot is oriented top-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBI | Low-battery detector input | Analog input referenced to GND; threshold set by external resistive divider; disabled in snooze mode. |
| GND | Ground reference | Primary return path for input, output, and internal circuitry; must be low-impedance connection to system ground plane. |
| C1− | Flying capacitor C1 negative terminal | Connects to negative side of 1 µF ceramic flying capacitor; forms half of push-pull charge transfer stage. |
| C1+ | Flying capacitor C1 positive terminal | Connects to positive side of 1 µF ceramic flying capacitor; switches 180° out-of-phase with C2 terminals. |
| OUT | Regulated 3.3-V output | Power rail for downstream loads; requires 2.2 µF ceramic output capacitor (Co) to maintain ripple <5 mVPP. |
| LBO | Open-drain low-battery output | Pulled low when LBI voltage drops below 1.18 V; requires external pullup (100 kΩ–1 MΩ) to OUT or logic rail ≤3.6 V. |
| SNOOZE | Mode control input | Drives three states: LOW = snooze (2 µA IQ), HIGH = normal (internal oscillator), AC = sync to external clock (400–800 kHz). |
| C2− | Flying capacitor C2 negative terminal | Connects to negative side of second 1 µF ceramic flying capacitor; complements C1 in push-pull energy transfer. |
| IN | Input power supply | Accepts 1.6–3.6 V battery source; bypassed with 2.2 µF ceramic capacitor (Ci) to suppress input impedance spikes. |
| C2+ | Flying capacitor C2 positive terminal | Connects to positive side of second 1 µF ceramic flying capacitor; switches 180° out-of-phase with C1 terminals. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60211DGSR | Same DGS package and 3.3-V/100-mA output, but replaces LBI/LBO with power-good (PG) output active at 90% VOUT. | Used where system startup sequencing or output voltage validation is required instead of battery monitoring. | Select TPS60211DGSR when power-good signaling (e.g., for FPGA configuration enable) is needed over low-battery warning. |
| TPS60212DGSR | Same low-battery detection function, but rated for 50 mA max output current and specified down to −40°C. | Suitable for cost-optimized or lower-current medical accessories where extended temperature range is mandatory. | Choose TPS60212DGSR only if 50 mA output suffices and industrial temperature grade (−40°C to 85°C) is required. |
Compared with TPS60211DGSR and TPS60212DGSR, HPA00210DGSR uniquely combines 100 mA output capability, low-battery detection, and full −40°C to 85°C operation - making it optimal for high-reliability portable diagnostics where both battery health monitoring and sustained load current are essential.

FAQ
What is the minimum input voltage required for HPA00210DGSR to start up and regulate?
The HPA00210DGSR begins regulation at 1.6 V input. During startup, it precharges the output capacitor until VOUT reaches 0.8 × VIN, then activates the charge pump stages. This ensures reliable turn-on even from deeply discharged batteries - critical for HPA00210DGSR deployments in glucose meters where battery voltage may drop to 1.6 V before replacement.
Does HPA00210DGSR require external inductors or transformers?
No, HPA00210DGSR is a capacitor-based charge pump and requires zero inductors. It uses two 1 µF ceramic flying capacitors (C1/C2), a 2.2 µF input capacitor (Ci), and a 2.2 µF output capacitor (Co) - all low-ESR X5R/X7R ceramics. This eliminates magnetic EMI and simplifies PCB layout, a key advantage of HPA00210DGSR in compact portable designs.
How does the snooze mode of HPA00210DGSR affect output voltage accuracy and load capability?
In snooze mode (SNOOZE = LOW), HPA00210DGSR maintains output regulation at 3.3 V ±6% with typical 2 µA quiescent current, but limits load current to 2 mA maximum. If load exceeds this, the device re-enters startup mode to restore full regulation - preserving battery life while ensuring HPA00210DGSR remains functional during brief wake events in medical wearables.
Can the low-battery detection threshold of HPA00210DGSR be adjusted, and how?
Yes, the LBI pin on HPA00210DGSR accepts an externally programmed voltage divider (R1/R2) to set the trip point between ~1.5 V and ~3.6 V. With VLBI = 1.18 V ±5%, recommended R1+R2 values range from 100 kΩ to 1 MΩ. For example, using R1 = 340 kΩ and R2 = 649 kΩ sets VTRIP ≈ 1.71 V for a 1.8-V nominal battery - a confirmed design practice documented for HPA00210DGSR in TI SLVS296.
What is the maximum allowable external clock frequency when synchronizing HPA00210DGSR?
The SNOOZE pin of HPA00210DGSR accepts external clock signals from 400 kHz to 800 kHz. Internally, the charge pump operates at half that frequency (200–400 kHz), matching the native oscillator range. Applying >800 kHz violates absolute maximum ratings and risks unstable regulation - a hard limit verified in HPA00210DGSR's electrical characteristics table (SLVS296, p.8).
